All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26 should be key in like 192168000026.  No decimal is needed).  5.  Key entry can not be deleted but the phone may prompt error once it is detected PLACING A PHONE CALL PHONE OR EXTENSION NUMBERS 1.  Dial the number directly and wait for 4 seconds (To change the default value, modify the following setting - “No Key Entry Timeout”)  or 2.  Dial the number directly and press # (Use # as dial key” must be configured in web configuration).  Examples: 1.  Dial a number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the phone number.  Press # or wait for 4 seconds.  Check with your VoIP service provider for further details on prefix numbers.  DIRECT IP CALLS Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.   Elements necessary to completing a Direct IP Call:  1.  Both GXW40XX and other VoIP Device, have public IP addresses, or  2.  Both GXW40XX and other VoIP Device are on the same LAN using private IP addresses, or  3.  Both GXW40XX and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).   GXW40XX supports two ways to make Direct IP Calling:  Using IVR 1.  Pick up the analog phone then access the voice menu prompt by dial “***” 2. Dial “47” to access the direct IP call menu 3.  Enter the IP address using format ex. 192*168*0*160 after the dial tone.   Using Star Code 1.  Pick up the analog phone then dial “*47” 2.  Enter the target IP address using same format as above. Note: NO dial tone will be played between step 1 and 2.  Destination ports can be specified by using “*” (encoding for “:”) followed by the port number.
 Grandstream Networks, Inc.  GXW40XX User Manual  Page 13 of 39    Firmware 1.0.4.2  Last Updated:  06/2011   Examples:  a)  If the target IP address is 192.168.0.160, the dialing convention is *47 or Voice Prompt with option 47, then 192*168*0*160.  followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the default destination port 5060 is used if no port is specified.   b)  If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be: *47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds.  NOTE:  When completing direct IP call, the “Use Random Port” should set to “NO”.  You can not make direct IP calls between FXS ports since they are using same IP.  CALL HOLD Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button). Press the “flash” button again to release the previously held Caller and resume conversation.  If no “flash” button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.   CALL WAITING Call waiting tone (2 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle between incoming call and current call by pressing the “flash” button.  First call is placed on hold.  Press the “flash” button to toggle between two active calls. CALL TRANSFER  BLIND TRANSFER Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:  3.  Caller A presses FLASH on the analog phone to hear the dial tone. 4.  Caller A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds). 5.  Caller A will hear the confirm tone. Then, A can hang up.  NOTE:   “Enable Call Feature” must be set to “Yes” in web configuration page. Caller A can place a call on hold and wait for one of three situations:    1.  A quick confirmation tone (similar to call waiting tone) followed by a dial tone.  This indicates the transfer is successful (transferee has received a 200 OK from transfer target).  At this point, Caller A can either hang up or make another call.  2.  A quick busy tone followed by a restored call (on supported platforms only).  This means the transferee has received a 4xx response for the INVITE and we will try to recover the call.  The busy tone is just to indicate to the transferor that the transfer has failed.  3. Continuous busy tone.  The phone has timed out. Note:  continuous busy tone does not indicate the transfer has been successful, nor does it indicate the transfer has failed.  It often means there was a failure to receive second NOTIFY – check firmware for most recent release.  ATTENDED TRANSFER Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C: 1.  Caller A presses FLASH on the analog phone for dial tone. 2.  Caller A then dials Caller C’s number followed by # (or wait for 4 seconds).
 Grandstream Networks, Inc.  GXW40XX User Manual  Page 14 of 39    Firmware 1.0.4.2  Last Updated:  06/2011  3.  If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to complete transfer. 4.  If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.   NOTE:  When Attended Transfer fails and A hangs up, the GXW40XX will ring back user A to remind A that B is still on the call.  A can pick up the phone to resume conversation with B. 3-WAY CONFERENCING The GXW40XX supports Bellcore style 3-way Conference.   Instructions for 3-way conference:  Assuming that call party A and B are in conversation. A (GXW40XX) wants to bring C in a conference:  1.  A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone. 2.  A dials C’s number then # (or wait for 4 seconds).  3.  If C answers the call, then A presses FLASH to bring B, C in the conference. 4.  If C does not answer the call, A can press FLASH back to talk to B.  5.  If A presses FLASH during conference, C will be dropped out.  6.  If A hangs up, the conference will be terminated for all three parties when configuration “Transfer on Conference Hangup” is set to “No”. If the configuration is set to “Yes”, A will transfer B to C so that B and C can continue the conversation. HUNTING GROUP This feature allows the user to setup a single SIP account on the gateway and have the ability to use all FXS ports to make/receive calls. Using this feature, all ports active in same Hunting Group will have the same phone number and incoming calls will be distributed in a round robin manner among the ports active in that Hunting Group.  The number of hunting groups is limited by the number of ports each GXW model has - i.e. each port can be its own Hunting Group.  The most practical and efficient way to use Hunting Groups is to assign 2 or 3 ports to separate Hunting Groups.   One additional and popular way to use the Hunting Group feature is called “multiplexed analog lines”. In this configuration, a legacy PBX system with 8 FXO trunks can be connected to 8 GXW 4008 ports configured as a Hunting Group. The GXW can be registered to a SIP server provider using only one phone number. If the SIP service provider allows multiple calls to the same number, the GXW will allow 8 concurrent calls to the same SIP number. All office members can be reached remotely using the same phone number in a round-robin fashion.  Example Configuration of a typical Hunting Group:  1.  Configure the SIP account from your VoIP Service Provider on FXS port 1 under FXS Ports webpage. 2. Select Active under the Hunting Group drop box for FXS port 1. 3.  For the remaining ports (say 2, 3 and 4) select 1 for Hunting Group. Ports 2, 3 and 4 are now active members of the hunting group associated with port 1.  This configuration will route all calls directed to FXS port 1 to ports 2, 3 and/or 4 in round robin fashion respectively if port 1 is busy or times out. You can configure the ring timeout on the Profile page.  Example configuration of a multiple Hunting Group:  FXS Port #1:  SIP UserID and Authenticate ID entered, Hunting group set to "Active"
 Grandstream Networks, Inc.  GXW40XX User Manual  Page 15 of 39   Firmware 1.0.4.2  Last Updated:  06/2011  FXS Port #2:  SIP UserID and Authenticate ID left blank, Hunting Group set to "1" FXS Port #3:  SIP UserID and Authenticate ID left blank, Hunting Group set to "1" FXS Port #4:  SIP UserID and Authenticate ID entered, Hunting group set to "Active" FXS Port #5:  SIP UserID and Authenticate ID left blank, Hunting Group set to "4" FXS Port #6:  SIP UserID and Authenticate ID left blank, Hunting Group set to "4" FXS Port #7:  SIP UserID and Authenticate ID entered, Hunting group set to "Active" FXS Port #8:  SIP UserID and Authenticate ID left blank, Hunting Group set to "7" … FXS Port #24:  SIP UserID and Authenticate ID left blank, Hunting Group set to "2"  Hunting Group 1 contains ports 1, 2, 3.  Hunting Group 4 contains ports 4, 5, 6.  Hunting Group 7 contains ports 7, 8.  Please be aware, the choice of 1 for ports 2 and 3, the choice of 4 for ports 5 and 6, the choice 7 for port 8 is required to indicate that the SIP account tied to port market as “Active”  will be used for all members of the same Hunting group. Needless to say, those members of the same Hunting group may not be sequential ports. In following example ports 3, 5 and 7 tied to SIP Account configured in Port #1 marked as “Active”, and ports 4,6,8 tied to SIP Account configured in Port #2 marked as “Active” as well.  Example of not sequential configuration of a multiple Hunting Group:  FXS Port #1:  SIP UserID and Authenticate ID entered, Hunting group set to "Active" FXS Port #2:  SIP UserID and Authenticate ID entered, Hunting Group set to "Active" FXS Port #3:  SIP UserID and Authenticate ID left blank, Hunting Group set to "1" FXS Port #4:  SIP UserID and Authenticate ID left blank, Hunting group set to "2" FXS Port #5:  SIP UserID and Authenticate ID left blank, Hunting Group set to "1" FXS Port #6:  SIP UserID and Authenticate ID left blank, Hunting Group set to "2" FXS Port #7:  SIP UserID and Authenticate ID left blank, Hunting group set to "1" FXS Port #8:  SIP UserID and Authenticate ID left blank, Hunting Group set to "2" … FXS Port #24: SIP UserID and Authenticate ID left blank, Hunting Group set to "2"  Note: A single call directed to the SIP account will NOT result in all ports ringing at the same time. They will ring in the hunting group only. This feature is applicable to incoming calls only. INTER-PORT CALLING In some cases a user may want to make phone calls between the phones connected to multiple ports of the same gateway when it is used as a stand alone unit, without the use of a SIP server. This feature will also be applicable when the gateway is used with Hunting Groups and is registered to SIP server only with one master number. In such cases users still will be able to make inter-port calls by using the IVR feature.   For example on the GX4004 and GXW4008 the user connected to port 1 can reach the user connected to port 3 by dialing *** and 73. Digit 7 indicated using inter-port calling feature, digit 3 indicates the port number which should be reached. At the same manner the user connected to port 4 can reach the user connected to port 8 by dialing *** and 78.   On the GXW4024 inter-port calling is achieved by dialing *** and 7 plus two extra digits corresponding to the port number. For example the user connected to port 1 can be reached by dialing *** and 701; the user connected to port 24 can be reached by dialing *** 724.
 Grandstream Networks, Inc.  GXW40XX User Manual  Page 16 of 39    Firmware 1.0.4.2  Last Updated:  06/2011  PSTN PASS THROUGH/LIFE LINE This feature is only applicable to GXW4004 and GXW4008 models.  The RJ-11 line jack on the GXW400X side connected to a legacy PSTN line, functions as a pass through jack when the GXW400X loses power or becomes unregistered. In this case, analog phone connected to FXS port 1 will be directly connected to RJ-11 jack marked as LINE.  The pass through/life line mode enables the user to use the analog phone for PSTN calls directly without using an access code.  SENDING AND RECEIVING FAX GXW40XX supports fax in two modes: 1) T.38 (Fax over IP) and 2) Fax Pass through. T.38 is the preferred method because it is more reliable and works well in most network conditions. If the service provider supports T.38, please use this method by selecting T.38 as fax mode (default).  If the service provider does not support T.38, pass-through mode may be used. If you have problems with sending or receiving Fax, toggle the Fax Tone Detection Mode setting. SUPPORT RADIUS PROTOCOL GXW40XX supports RADIUS for authentication, authorization and billing purposes. Primary and secondary RADIUS server configurations are available to provide redundancy to this feature. In case Primary Radius server becomes unusable, RADIUS requests will be automatically sent to the secondary server. When at least one RADUIS server was configured, the device will allow users to make phone calls only after authorization from RADIUS server has been received. CDR (Call Detail Record) is also sent to the RADIUS server for billing purposes. RAIDUS server can send requests to terminate calls when run out of pre-paid credit.  The GXW400x will be able to work in VoIP billing environment using redundant double server configuration. User will be able to configure primary and secondary RADUIS server IP Addresses or FQDNs. Once at least one RADUIS server was configured, the device will allow users to make phone calls only after permission from RADIUS server has been received. In case Primary Radius server becomes unusable, secondary will take role of primary and will manage credit recourses in the network. Imbedded RADIUS client also supports request generated by Radius server to terminate calls when run out of pre-paid credit.

Please reference the GUI pages using the following link: http://www.grandstream.com/products/gxw_series/gxw40xx/documents/gxw40xx_gui.zip .   IMPORTANT SETTINGS The end-user must configure the following settings according to the local environment.    NOTE:  Most settings on the web configuration pages are set to the default values.  NAT Settings If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN Server. The following three (3) settings are useful in the STUN Server scenario: 1.  STUN Server (under Advanced Settings webpage) Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank. 2.  Use Random Ports (under Advanced Settings webpage) It really depends on your network settings, so set this parameter to Yes or No, whichever works.  Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a Public IP address, set this parameter to No. 3.  NAT Traversal (under the Profile web pages) Set this to Yes when gateway is behind firewall on a private network.  DTMF Methods DTMF Settings are in Profile pages. • DTMF in-audio •  DTMF via RTP (RFC2833) •  DTMF via SIP INFO  You can enable set priority of DTMF methods according to your preference, from Priority 1 to 3. This setting should be based on your server DTMF setting.

 Grandstream Networks, Inc.  GXW40XX User Manual  Page 28 of 39    Firmware 1.0.4.2  Last Updated:  06/2011  Hunting Group  This feature enables the gateway to register all existing FXS ports with the same phone number. Each incoming call will be routed to first available port in round robinmode. User may configure all ports as members of the same Hunting Group or it may configure different port combinations for more than one Hunting Group.   For example:  Ports 1, 3 and 5 are members of the same Hunting Group, the rest of the ports may have separate numbers and may be reached independently.   Any port, member of a Hunting Group that is not registered with a SIP account, will be able to place outbound calls using the SIP credentials of the primary Hunting Group port.   For example: Port 1, 3 and 5 are members of the same Hunting Group.  Port 1 is registered with a SIP account. Ports 3 and 5 are not registered.  Ports 3 and 5 will be able to place outbound calls using the SIP account of port 1.  Select appropriate value for Hunting Group feature. The original SIP account should be set to Active while the group members should be set to the port number of the Active Port.   Example configuration of a multiple Hunting group:  FXS Port #1:  SIP UserID and Authenticate ID entered, Hunting group set to "Active" FXS Port #2:  SIP UserID and Authenticate ID left blank, Hunting Group set to "1" FXS Port #3:  SIP UserID and Authenticate ID left blank, Hunting Group set to "1" FXS Port #4:  SIP UserID and Authenticate ID entered, Hunting group set to "Active" FXS Port #5:  SIP UserID and Authenticate ID left blank, Hunting Group set to "4" FXS Port #6:  SIP UserID and Authenticate ID left blank, Hunting Group set to "4" FXS Port #7:  SIP UserID and Authenticate ID entered, Hunting group set to "Active" FXS Port #8:  SIP UserID and Authenticate ID left blank, Hunting Group set to "7" Hunting Group 1 contains ports 1, 2, 3.

Primary SIP Server  Primary SIP Server’s IP address or Domain name provided by VoIP service provider. Failover SIP Server  Failover SIP Server’s IP address or Domain name provided by VoIP Service provider. This server will be used if the Primary SIP server becomes unavailable. Prefer Primary SIP Server  Default is no. If set to yes it will register to Primary Server if registration with Failoverserver expires Outbound Proxy  IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border Controller. Used by GXW40XX for firewall or NAT penetration in different network environments.  If symmetric NAT is detected, STUN will not work and ONLY outbound proxy can correct the problem. SIP transport  User can select UDP or TCP or TLS. Please make sure you’re SIP Server or network environment supports SIP over the selected transport method. Default is UDP. NAT Traversal  This parameter defines whether the GXW40XX NAT traversal mechanism is activated or not.  If activated (by choosing “Yes”) and a STUN server is also specified, then the GXW40XX performs according to the STUN client specification. Under this mode, the embedded STUN client will detect if and what type of firewall/NAT is being used.  If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXW40XXwill use its mapped public IP address and port in all of its SIP and SDP messages.    If the NAT Traversal field is set to “Yes” with no specified STUN server, the GXW40XXwill periodically (every 20 seconds) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.  DNS Mode  One from the 3 modes available for “DNS Mode” configuration: -A Record (for resolving IP Address of target according to domain name) -SRV (DNS SRV resource records indicates how to find services for various protocols) -NAPTR/SRV (Naming Authority Pointer according to RFC 2915) One mode can be chosen for the client to look up server. The default value is “A Record” User ID is Phone Number  If the GXW40XX has an assigned PSTN telephone number, this field should be set to “Yes”.  Otherwise, set it to “No”.  If “Yes” is set, a “user=phone” parameter will be attached to the “From” header in SIP request. SIP Registration  This parameter controls whether the GXW40XX needs to send REGISTER messages to the proxy server. The default setting is “Yes”.   Unregister on Reboot  Default is No.  If set to “Yes”, the SIP user’s registration information is cleared on reboot.Outgoing Call without Registration  Default is No.  If set to “Yes,” user can place outgoing calls even when not registered (if allowed by Internet Telephone Service Provider) but is unable to receive incoming calls.   Any port, member of a Hunting Group that is not registered with a SIP account, will be able to place outbound calls using the SIP credentials of the primary Hunting Group port.  For example: Port 1, 3 and 5 are members of the same Hunting Group.  Port 1 is registered with a SIP account. Ports 3 and 5 are not registered.  Ports 3 and 5 will be able to place outbound calls using the SIP account of port 1, even if Outgoing Call without Registration is set to No Register Expiration  Allows the user to specify the time frequency (in minutes) for the GXW40XX to refresh its registration with the specified registrar. The default interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days).

When configured, channel 0 will use this port _value for RTP and the port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP, port_value+3 for its RTCP and so on. The default value for Profile 1 is 5004 and 6004 for Profile 2. Use random port  Default is No. If set to Yes, the device will pick randomly-generated SIP and RTP ports. This is usually necessary when multiple GXW40XX/HT50X are behind the same NAT. Refer to Use Target Contact  Default is No. If set to YES, then for Attended Transfer, the “Refer-To” header uses the transferred target’s Contact header information.   Transfer on Conference  Hang up Default is No. In which case if conference originator hangs up the conference will be terminated. When option YES is chosen, originator will transfer other parties to each other so that B and C can choose either to continue the conversation or hang up.  Enable Ring-Transfer  Default is No, this will create a Semi-Attendant Transfer. When set to Yes, device can transfer the call upon receiving ring back tone. Disable Bellcore Style 3-Way Conference  Default is No. you can make a Conference by pressing ‘Flash’ key. If set to Yes, you need to dial *23 + second callee number. Remove OBP from Route Header:  Default is No. If set to Yes, the Outbound Proxy will be removed from the route header. Support SIP Instance ID  Default is Yes. If set to Yes, the contact header in REGISTER request will contain SIP Instance ID as defined in IETF SIP Outbound draft. Validate incoming SIP message  Default is No. If set to yes all incoming SIP messages will be strictly validated according to RFC rules. If message does not pass validation process, call will be rejected. Check SIP user ID for incoming INVITE  Default is No. Check the SIP User ID in Request URI. If they don’t match, the call will  be rejected. Allow Incoming SIP Messages from SIP Proxy Only Default is No. If incoming SIP message does not match with SIP Server, it will be rejected. SIP T1 Timeout  T1 is an estimate of the round-trip time between the client and server transactions.  If the network latency is high, select larger value for more reliable usage. SIP T2 Interval  Maximum retransmission interval for non-INVITE requests and INVITE responses. DTMF Payload Type  Sets the payload type for DTMF using RFC2833. Preferred DTMF method (in listed order) The GXW40xx supports up to 3 different DTMF methods including in-audio, via RTP (RFC2833) and via Sip Info.

 Grandstream Networks, Inc.  GXW40XX User Manual  Page 31 of 39    Firmware 1.0.4.2  Last Updated:  06/2011  Use NAT IP  NAT IP address used in SIP/SDP message. Default is blank. Distinctive Ringtone  Custom Ring Tone 1 to 3 with associate Caller ID: when selected, if Caller ID is configured, then the device will ONLY uses this ring tone when the incoming call is from the Caller ID.  System Ring Tone is used for all other calls.  When selected but no Caller ID is configured, the selected ring tone will be used for all incoming calls. Distinctive ring tones can be configured not only for matching whole number, but also for matching prefixes. In this case symbol * (star) will be used.   If server supports Alert-Info header and standard ring tone set (Bellcore) or distinctive ring tone 1-10 is specified, then the ring tone in the Alert-Info header from server will be used.  For example: If configured as *617, Ring Tone 1 will be used in case of call arrived from Massachusetts. Any other incoming call will ring using cadence defined in parameter System Ring Cadence located under Advanced Settings Configuration page. Disable Call Waiting  Default is No. If set to YES Call Waiting indication information will not be provided to analog phone connected to this FXS port. Disable Call Waiting Caller ID  Default is No. If set to YES Call Waiting caller ID will not be provided to analog phone  connected to this FXS port. Disable Call Waiting Tone  Default is No. This is to disable the stutter Call Waiting Tone when a Call Waiting call arrives. The CWCID will still be displayed. Disable Reminder Ring for On-Hold Call  Default is No. This is to disable the Reminder Ring that is played when a call is waiting on hold and the analog phone goes on-hook. Disable Visual MWI  Visual message indicator is a special on-hook caller ID type message that enables and disables the message waiting light on certain phones. GXW40XX has this feature enabled by default. However, certain phones (rare) that do not support it may mistakenly treat this CID signal as an incoming call. A configuration option is needed to turn on MWI in this case. Visual MWI Type  This is the type of signal sent to the analog phone to make it turn the lamp ON upon receiving a Voice mail. Check the phone’s manual to find out what signal is supported, FSK (default) or Neon. Note: This is only supported in model GXW4024 ver 4.A or newer. Ring Timeout  Incoming call will stop ringing when not picked up given a specific period of time. Hunting Group Ring Timeout  Default is 20 seconds. If call is not answered within this designated time period, the call will be forwarded to the next member of a Hunt Group. Delayed Call Forward Wait Timeout  Default value is 20 seconds. In case this feature activated using * codes (*92 code), the call will be forwarded after this preconfigured amount of time. No Key Entry Timeout  Default is 4 seconds. Call will be completed within this time interval if no additional key entry occurs.  Early Dial  Default is No.  Use only if proxy supports 484 response.  This parameter controls whether the phone will send an early INVITE each time a key is pressed when a user dials a number.  If set to “Yes”, an INVITE is sent using the dial-number collected thus far;  Otherwise, no INVITE is sent until the “(Re-)Dial” button is pressed or after about 5 seconds have elapsed if the user forgets to press the “Re-Dial” button.  The “Yes” option should be used ONLY if there is a SIP proxy configured and the proxy server supports 484 Incomplete Address response. Otherwise, the call will likely be rejected by the proxy (with a 404 Not Found error).    This feature is NOT designed to work with and should NOT be enabled for direct IP-to-IP calling.

When GXW40XX boots up, it will send TFTP or HTTP request to download configuration file, “cfg000b82xxxxxx” or “cfg000b82xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the GXW40XX. It will first request “cfg000b82xxxxxx” then “cfg000b82xxxxxx.xml”  A service provider or an enterprise with large deployment of Grandstream devices can easily manage the configuration and service provisioning of individual devices remotely from a central server.   Grandstream has a central provisioning system called GAPS (Grandstream Automated Provisioning System). GAPS supports automatic configuration of Grandstream devices.  GAPS uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual Grandstream device.   Grandstream provides GAPS service to VoIP service providers.  Use GAPS for either simple redirection or with certain special provisioning settings.  At boot-up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer’s TFTP or HTTP server for further provisioning.  Grandstream also provide GAPSLITE software package which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating device configuration files.    The GAPSLITE configuration tool is now free to end users. The tool and configuration template are available for download from http://www.grandstream.com/support/tools  .
 Grandstream Networks, Inc.  GXW40XX User Manual  Page 36 of 39    Firmware 1.0.4.2  Last Updated:  06/2011  SOFTWARE UPGRADE   Software upgrade can be done via either TFTP or HTTP/HTTPS. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.   Firmware Upgrade through TFTP/HTTP/HTTPS  To upgrade via TFTP or HTTP/HTTPS, the “Firmware Upgrade and Provisioning upgrade via” field needs to be set to TFTP, HTTP or HTTPS, respectively.  “Firmware Server Path” needs to be set to a valid URL of a TFTP or HTTP/HTTPS server, server name can be in either FQDN or IP address format. Here are examples of some valid URL.                firmware.mycompany.com:6688/Grandstream/1.0.4.2 or   72.172.83.110   NOTES: y  Firmware upgrade server in IP address format can be configured via IVR.  Please refer to the CONFIGURATION GUIDE section for instructions. If the server is in FQDN format, it must be set via the web configuration interface.  y  Grandstream recommends end-user use the Grandstream HTTP server. Its address can be found at http://www.grandstream.com/support/firmware . Currently the HTTP firmware server IP address is 72.172.83.110.  For large companies, we recommend to maintain their own TFTP/ HTTP/HTTPS server for upgrade and provisioning procedures.  y  Once a “Firmware Server Path” is set, user needs to update the settings and reboot the device. If the configured firmware server is found and a new code image is available, the GXW will attempt to retrieve the new image files by downloading them into the GXW400x ’s SRAM. During this stage, the GXW’s LEDs will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will then be saved into the Flash. If TFTP/HTTP/HTTPS fails for any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the GXW will stop the TFTP/HTTP/HTTPS process and simply boot using the existing code image in the flash.  y  Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes if it is performed on a LAN.  It is recommended to conduct firmware upgrade in a controlled LAN environment if possible. For users who do not have a local firmware upgrade server, Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade. y  Grandstream’s latest firmware is available http://www.grandstream.com/support/firmware .  Oversea users are strongly recommended to download the binary files and upgrade firmware locally in a controlled LAN environment.   y  Alternatively, user can download a free TFTP or HTTP server and conduct local firmware upgrade. A free windows version TFTP server is available for download from http://support.solarwinds.net/updates/New-customerFree.cfm.  Our latest official release can be downloaded from http://www.grandstream.com/y-firmware.htm.    Instructions for local firmware upgrade:  1.  Unzip the file and put all of them under the root directory of the TFTP server.  2.  Put the PC running the TFTP server and the GXW40XX device in the same LAN segment.
 Grandstream Networks, Inc.  GXW40XX User Manual  Page 37 of 39    Firmware 1.0.4.2  Last Updated:  06/2011  3.  TFTP server's security settings should be changed from "Receive Only" to "Transmit Only" for the firmware upgrade.  4.  Configure the Firmware Server Path with the IP address of the PC 5.  Update the change and reboot the unit.  CONFIGURATION FILE DOWNLOAD Grandstream SIP Device can be configured via Web Interface as well as via Configuration File through TFTP or HTTP/HTTPS. “Config Server Path” is the TFTP or HTTP/HTTPS server path for configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be same or different from the “Firmware Server Path”.  A configuration parameter is associated with each particular field in the web configuration page.  A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers.  i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page.  For a detailed parameter list, please refer to the corresponding firmware release configuration template.   When Grandstream Device boots up or reboots, it will issue request for configuration file named “cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the LAN side MAC address of the device, i.e., “cfg000b820102ab”. The configuration file name should be in lower cases.  FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix.  This makes it possible to store ALL of the firmwares with different version in one single directory.  Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory.  In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is selected, the device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix. MANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD  When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 to have the devices periodically check with either Firmware Server or Config Server, whenever they are defined.  This allows the device periodically check whether there is any new changes need to be taken, similar to the AntiVirus Software to upgrade the Virus Definition files. Screenshot is below:   Automatic Upgrade:                 No      Check every day      Check every week                  Hour of the day(0-23):  1    Day of the week(0-6):  1   If automatic upgrade is enabled, service provider can further customize the behavior and distribute server load by setting hour of the day and/or day of the week for upgrade.
