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)
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 Profile web pages)
Set this to Yes
when gateway is behind firewall on a private network.
DTMF
METHODS
DTMF Settings are in FXS portX pages
.
• DTMF in-audio
• DTMF via RTP (RFC2833)
• DTMF via SIP INFO
Set priority of DTMF methods according to your preference. This setting should be based on your server
DTMF setting.
