Open and tap on Factory Reset to restore the GXV3275 to factory default settings.  Developer mode.This mode can be used via ADB tool for advanced debugging purpose. MulticastPagingThe GXV3275 supports the multicast paging which allows different SIP users to listen to a page from a common multicast IP address.  Paging Barge For the following we will assume that the option “Paging Priority Active” is not checked - We suppose that we have 5 listening addresses filled on the GVX3275, from priority 1 to 5, and Paging Barge is set to "2", only priority 1 and 2 multicasts will hold the call and play multicast. For the multicast 3/4/5 have no priority to "cover/override" the call. - If Paging Barge is set to "Disable", no multicast can be prior to the call, which means the call is the highest priority.  Paging Priority Active - We suppose that we have 5 listening addresses filled on the GVX3275, from priority 1 to 5, and Paging Priority Active is set to "Yes", low priority multicast will be "covered/overridden" by higher priority ones. - For example, the GXV3275 is listening to a multicast from priority 2 address, only priority 1 multicast can override the current multicast, but priority 3/4/5 multicast will be ignored. - If we have 5 listening addresses filled in GXV3275, from priority 1 to 5, and Paging Priority Active is set to "No", no new multicast can override the current one no matter what priority it has. - For example, GXV3275 is listening to a multicast from address 4, priority 1/2/3/5 multicast will all be ignored.

GXV3275 Administration Guide Version 1.0.3.186 Page |46 AccountPageDefinitionsGXV3275has six lines that can be configured to accommodate6 independent SIP accounts. Each SIP account has an individual configuration page. Account/GeneralSettingsAccount Active Indicates whether the account is active. The default value for the IPVideoTalk account (Account 6) is "Yes" and the default value for the first five accounts is "No". Account Name Configures the name associated with each account to be displayed on the LCD. Note: the account name will be trimmed automatically to remove whitespaces and tabulations at the begging and end of the string, for ex if the account name set to “account1 “ it will be automatically corrected to “account1”. SIP Server Specifies the URL or IP address, and port of the SIP server. This should be provided by VoIP service providers (ITSP). SIP User ID Configuresuser account information provided by your VoIP service provider (ITSP). It's usually in the form of digits similar to phone number or actually a phone number. SIP Authentication ID Configures the SIP service subscriber's Authenticate ID used for authentication. It can be identical to or different from the SIP User ID. SIP Authentication Password Configures the account password required for the phone to authenticate with the ITSP (SIP) server before the account can be registered. After saving, it will appear as hidden for security purpose. Voice Mail Access Number Sets if the phone system allows users to access the voice messages by pressing the MESSAGE key on the phone. This ID is usually the VM portal access number. For example, in UCM6100 IPPBX, *97 could be used. Name Specifies the SIP server subscriber's name (optional) that will be used for Caller ID display. The configured content will be included in the From, Contact and P-Preferred-Identity headers of SIP INVITE message. Show Account Name Only Enables to display the account name; if it is checked, the user ID will be hidden and the account name will be displayed only. Tel URI Indicates E.164 number in “From” header by adding “User=Phone” parameter or using “Tel:” in SIP packets, if the phone has an assigned PSTN Number.  Disabled: Will use “SIP User ID” information in the Request-Line and “From” header.  User=Phone:“User=Phone” parameter will be attached to the Request-Line and “From” header in the SIP request to indicate the E.164 number. If set to "Enable".
GXV3275 Administration Guide Version 1.0.3.186 Page |47  Enabled: "Tel:" will be used instead of "sip:" in the SIP request. Please consult your carrier before changing this parameter. Default is “Disabled”. Account/NetworkSettingsOutbound Proxy Configures the IP address or the domain name of the primary outbound proxy, media gateway or session border controller. It's used by the phone for firewall or NAT penetration in different network environments. If a symmetric NAT is detected, STUN will not work and only an outbound proxy can provide a solution Secondary Outbound Proxy Sets IP address or domain name of the secondary outbound proxy, media gateway or session border controller. The phone system will try to connect the Secondary outbound proxy only if the primary outbound proxy fails. DNS Mode Defines which DNS service will be used to lookup IP address for SIP server’s hostname. There are three modes:  A Record  SRV  NATPTR/SRV To locate the server by DNS SRV set this option to "SRV" or "NATPTR/SRV". Default setting is "A Record". DNS SRV Fail-over Mode The option will decide which IP is going to be used in sending subsequent SIP packets (ex: Register refresh requests) after the list of IPs for SIP server host is resolved with DNS SRV. Default (prefer server with lowest SRV priority): The phone will always prefer to send SIP requeststo the available server having the lowest priority, and in case it’s down it contacts the next one, but once the server having lowest priority is UP again, the phone will switch over to this one. Saved one until DNS TTL (Stay on responding IP until DNS timeout): On this mode, the phone will resolve DNS SRV records and tries to send the request to the server having lowest priority and if it doesn’t respond, it will move on to the next IP until one of the servers responds, once this happen the phone will keep contacting this responding IP until DNS timeout (30 minutes) before starting over. Saved one until no response (Stay on responding IP until its failure): On this mode, the phone will send SIP requests to the last responding IP,and it doesn’t failover/switchover to the next one until this responding server is down.
GXV3275 Administration Guide Version 1.0.3.186 Page |48 NAT Traversal Specifies which NAT traversal mechanism will be enabled on the phone system. It can be selected from the dropdown list:  NAT NO  STUN  Keep-alive  UPnP  Auto  VPN If the outbound proxy is configured and used, it can be set to “NAT NO”. If set to "STUN" and STUN server is configured, the phone system will periodically send STUN message to the SUTN server to get the public IP address of its NAT environment and keep the NAT port open. STUN will not work if the NAT is symmetric type. If set to “Keep-alive”, the phone system will send the STUN packets to maintain the connection that is first established during registration of the phone. The “Keep-alive” packets will fool the NAT device into keeping the connection open and this allows the host server to send SIP requests directly to the registered phone. If it needs to use OpenVPN to connect host server, it needs to set it to “VPN”. If the firewall and the SIP device behind the firewall are both able to use UPNP, it can be set to “UPNP”. The both parties will negotiate to use which port to allow SIP through. The default setting is "Keep-alive". Proxy-Require Adds the Proxy-Required header in the SIP message. It is used to indicate proxy-sensitive features that must be supported by the proxy. Do not configure this parameter unless this feature is supported on the SIP server. Account/SIPSettingsSIP Registration Allows the phone system to send SIP REGISTER messages to the proxy/server. The default setting is "Yes". Unregister Before New Registration Controls whether to clear SIP user’s information by sending un-register request to the proxy server. When set to "All",the un-registration is performed by sending a REGISTER message with “Contact” header set to * and Expires=0 parameters to the SIP serverwhen the phone starts pre-registration after rebooting. If set to "Instance", the phone only cleans the current SIP user's info by sending REGISTER message with “Contact” header set to concerned SIP user’s info and Expires=0 parameters to the SIP server. The default setting is "Instance".
GXV3275 Administration Guide Version 1.0.3.186 Page |49 Register Expiration (m) Configures the time period (in minutes) in which the phone refreshes its registration with the specified registrar. The default setting is 60. The maximum value is 64800 (about 45 days). Re-register before Expiration (s) Specifies the time frequency (in seconds) that the phone sends re-registration request before the Register Expiration. The default setting is 0. The range is from 0 to 64,800. Registration Retry Wait Time (s) Configures the time period (in seconds) in which the phone will retry the registration process in the event that is failed.

SUBSCRIBE for MWI Configures the phone system to subscribe voice message service. If it is set to "Yes", the phone system will periodically send SIP SUBSCRIBE message for Message Waiting Indication service. GXV3275 phone system supports both synchronized and non-synchronized MWI. The default setting is "No". Enable SIP OPTIONS Keep Alive Enables SIP OPTIONS to track account registration status so the phone will send periodic OPTIONS message to server to track the connection status with the server. The default setting is "No". SIP OPTIONS Keep Alive Interval (s) Configures the time interval when the phone sends OPTIONS message to SIP server. The default setting is 30 seconds, which means the phone will send an OPTIONS message to the server every 30 seconds. The default range is 1-64800. SIP OPTIONS Keep Alive Maximum Tries Configures the maximum times of sending OPTIONS message consistently from the phone to server. Phone will keep sending OPTIONS messages until it receives response from SIP server. The default setting is "3", which means when the phone sends OPTIONS message for 3 times, and SIP server does not respond this message, the phone will send RE-REGISTER message to register again. The valid range is 3-10. Enable Session Timer Allows the phone system to use the session timer, when set to “Yes”, it will be added in the SIP INVITE message to notify the server.
GXV3275 Administration Guide Version 1.0.3.186 Page |50 Session Expiration (s) Configures the phone system’s SIP session timer. It enablesSIP sessions to be periodically "refreshed" via a SIP request (UPDATE, or re-INVITE). If there is no refresh via an UPDATE or re-INVITE message, the session will be terminated once the session interval expires. Session Expiration is the time (in seconds) where the session is considered timed out, provided no successful session refresh transaction occurs beforehand. The default setting is 180. The valid range is from 90 to 64800. Min-SE (s) Determines the minimum session expiration timer (in seconds) if the phone act as a timer refresher. The default setting is 90. The valid range is from 90 to 64800. UAC Specify Refresher Sets which party will refresh the active session if the phone makes outbound calls. If it is set to “UAC” and the remote party does not support Refresher feature, the phone system will refresh the active session. If it is set to “UAS”, the remote party will refresh it. If it is set to “Omit”, the header will be omitted so that it can be selected by the negotiation mechanism. The default setting is "Omit". UAS Specify Refresher Specifies which party will refresh the active session if the phone receives inbound calls. If it is set to “UAC”, the remote party will refresh the active session. If it is set to “UAS” and the remote party does not support refresh feature, the phone system will refresh it. The default setting is "UAC". Force INVITE Sets the SIP message type for refresh the session. If it is set to “Yes”, the Session Timer will be refreshed by using the SIP INVITE message. Otherwise, the phone system will use the SIP UPDATE or SIP OPTIONS message. Default is "No". Caller Request Timer Sets the caller party to act as refresher by force. If set to "Yes" and both party support session timers, the phone will enable the session timer feature when it makes outbound calls. The SIP INVITE will include the content “refresher=uac”. The default setting is "No". Callee Request Timer Sets the callee party to act as refresher by force. If set to "Yes" and the both parties support session timers, the phone will enable the session timer feature when it receives inbound calls. The SIP 200 OK will include the content “refresher=uas”. The default setting is "No". Force Timer Configures the session timer feature on the phone system by force. If it is set to "Yes", the phone will use the session timer even if the remote party does not support this feature. If it is set to "No", the phone will enable the session timer only when the remote party supports this feature. To turn off the session timer, select "No". The default setting is "No".
GXV3275 Administration Guide Version 1.0.3.186 Page |51 Enable 100rel Actives PRACK (Provisional Acknowledgment) method. PRACK improves the network reliability by adding an acknowledgement system to the provisional Responses (1xx).

If set to "No", it will always be omitted.The default setting is "Default". Use P-Preferred-Identity Header Specifies if the P-Preferred-Identity Header will be presented in the SIP INVITE message. If set to “default", the P-Preferred-Identity Header will be omitted in SIP INVITE message when "Huawei IMS" special feature is active. If set to "Yes", the P-Preferred-Identity Header will always be presented. If set to "No", it will be omitted. The default setting is "Default".Ignore Alert-Info header Configures the default ringtone. If set to “yes”, the incoming alert info header from the SIP server will be ignored and default configured ringtone will be played. The default setting is “No”. SIP Transport Determines which network protocol will be used to transport the SIP message. It can be selected from TCP/UDP/TLS. Default setting is "UDP".SIP URI Scheme When Using TLS Defines which SIP header, "sip" or "sips", will be used if TLS is selected for SIP Transport. The default setting is "sip". Use Actual Ephemeral Port in Contact with TCP/TLS Determines the port information in the Via header and Contact header of SIP message when the phone system use TCP or TLS. If set to No, these port numbers will use the permanent listening port on the phone. Otherwise, they will use the ephemeral port for the particular connection. The default setting is "No". Symmetric RTP Configures if the phone system enables the symmetric RTP mechanism. If it is set to “Yes”, the phone system will use the same socket/port for sending and receiving the RTP messages. The default setting is "No".

GXV3275 Administration Guide Version 1.0.3.186 Page |98 NoLocalFirmwareServersService providers should maintain their own firmware upgrade servers. For users who do not have a TFTP/HTTP/HTTPS server, some free Windows version TFTP servers are available for download from: http://www.solarwinds.com/free-tools/free-tftp-serverand http://tftpd32.jounin.net/. Please check our web site athttp://www.grandstream.com/support/firmwareforlatestfirmware.Instructions for local firmware upgrade via TFTP: 1. Unzip the firmware files and put all of them in the root directory of the TFTP server; 2. Connect the PC running the TFTP server and the GXV3275 device to the same LAN segment; 3. Launch the TFTP server and go to the File menuConfigureSecurity to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade; 4. Start the TFTP server and configure the TFTP server in the phone’s web configuration interface; 5. Configure the Firmware Server Path to the IP address of the PC; 6. Update the changes and reboot the GXV3275. End users can also choose to download a free HTTPserver fromhttp://httpd.apache.org/or use Microsoft IIS web server. ProvisioningandConfigurationFileDownloadGrandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP or HTTP/HTTPS. The "Config Server Path" is the TFTP, HTTP or HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The "Config Server Path" can be the 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 the “Admin Password” in the Web GUIMaintenanceWeb/SSH Access page. For a detailed parameter list, please refer to the corresponding firmware release configuration template in the following link: http://www.grandstream.com/support/tools When the GXV3275 boots up, it will issue TFTP or HTTP request to download a configuration XML file named "cfgxxxxxxxxxxxx" followed by "cfgxxxxxxxxxxxx.xml", where"xxxxxxxxxxxx" is the MAC address of the phone, i.e., "cfg000b820102ab" and "cfg000b820102ab.xml". If downloading "cfgxxxxxxxxxxxx.xml" file is not successful, the provision program will download a generic cfg.xml file. The configuration file name should be in lower case letters. For more details on XML provisioning, please refer to the following document: http://www.grandstream.com/sites/default/files/Resources/gs_provisioning_guide.pdf
