P a g e | 21 HT812/HT814 User Guide NAT Settings If you plan to keep the Handy Tone within a private network behind a firewall, we recommend using STUN Server. The following three 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 SIP/RTP Ports (under advanced settings webpage) This setting depends on your network settings. 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 FXS web page) Set this to Yes when gateway is behind firewall on a private network. DTMF Methods The HT812/HT814 support the following DTMF mode:  DTMF in-audio  DTMF via RTP (RFC2833)  DTMF via SIP INFO Set priority of DTMF methods according to your preference.

P a g e | 27 HT812/HT814 User Guide CALL OPERATIONS Placing a phone call To make the outgoing calls using your HT812/HT814 1. Pick up the handset of the connected phone. 2. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or 3. Dial the number directly and press # (Use # as dial key” must be configured in web configuration). Examples: 1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds. 2. Dial an outside 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:  Both HT812/HT814 and other VoIP Device, have public IP addresses, or  Both HT812/HT814 and other VoIP Device are on the same LAN using private IP addresses, or  Both HT812/HT814 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ). The HT812/HT814 support two ways to make Direct IP Calling: Using IVR 1. Pick up the analog phone then access the voice menu prompt by dialing “***” 2. Dial “47” to access the direct IP call menu 3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling” Using Star Code 1. Pick up the analog phone then dial “*47” 2. Enter the target IP address. Note: NO dial tone will be played between step 1 and 2 and destination ports can be specified using “*” (encoding for “:”) followed by the port number.

P a g e | 28 HT812/HT814 User Guide Examples of Direct IP Calls: 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 SIP/RTP Port” should set to “NO”. You cannot make direct IP calls between FXS1 to FXS2 since they are using same IP. Call Hold You can 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).

This makes it the possible to store all of the firmware 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.

P a g e | 32 HT812/HT814 User Guide In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, 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 “Yes, every” the auto check will be done in the minute specified in this field. If set to “daily at hour (0-23)”, Service Provider can use P193 (Auto Check Interval) to have the devices do a daily check at the hour set in this field with either Firmware Server or Config Server. If set to “weekly on day (0-6)” the auto check will be done in the day specified in this field. This allows the device periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time 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 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 "New Password" in the Web GUI->Maintenance->Web/SSH Access page->Admin Password.
