Setup SIP Switch

Each UI can connect to as many SIP Switch as you want. These SIP Switches can be running in different servers also. Each Class 4 switch has a telnet port and this telnet port enable the UI to communicate with it.

Here is how you need to do to setup the SIP Switch:

Click on VoIP Gateway on right side

In the VoIP Gateway page, you can specify the telnet IP and port to access to the dnl_softswitch instance:

Each dnlsoftswitch instance can listen to multiple SIP IP:port. You can click on + to add as many SIP IP:port combination as you need.

After you modify the VoIP gateway, you will need to restart dnl_softswitch instance in order for the change to take place.

You can use the following command to check if the SIP port is live or not:

[root@ns505183 ~]# netstat -anp |grep 5060
udp        0      0 198.27.82.144:5060      0.0.0.0:*                           27257/dnl_softswitc 
[root@ns505183 ~]# netstat -anp |grep 5080
