Enable Support of SIP Proxy Server / Soft Switch
Enable Support of SIP Proxy Server / Soft Switch: Enable the functions to inter-work with Proxy
Server / Soft Switch. When SIP Proxy 1 and 2 are enabled, the system will register to SIP Proxy 2 after
all lines have failed to register to SIP Proxy 1. SIP Proxy 2 is a backup system.
Proxy Server IP/Domain: Enter the Proxy Server IP address or URL (Uniform Resource Locator). You
can set three redundant Proxy IPs separated by semicolons.
Example: 61.123.231.1;12.34.56.78;proxy.sip.sip
Proxy Server Port: Enter the Proxy Server listen port number. (The default value is 5060)
Proxy Server Realm: This variable is used for gateway SIP account authentication in a SIP server. In
most cases, the gateway can automatically detect your SIP server realm. So you can leave this option
blank. However, if your SIP server requires you to use a specific realm you can manually enter it here.
If you fail to make a call, please contact your VoIP service provider.
TTL (Registration interval) [10-7200 s]: Enter the desired time interval at which the gateway will
report to your Proxy Server.
SIP Domain/Use Domain to Register: Enter the correct SIP domain to avoid registration failure (it is
not necessary to set this with some Proxy Servers). If you enable “Uses Domain to Register” the VoIP
gateway will register to the proxy with the domain name you filed. Otherwise the VoIP Gateway will
register to a Proxy with the IP it resolves. If you fail to make a call, please contact your VoIP
service provider.
