To change SIP port go to Settings > Asterisk SIP Settings > Chan SIP. This port cannot be the same as the PJSIP port setting at Settings > Asterisk SIP Settings > Chan PJSIP. You will need to reboot the server or restart Asterisk for these changes to take effect.

2.1.1. Test

On a SIP phone:

  • Enter the username (username = user extension #) and password you set up in the previous section.
  • Point the SIP phone to the IP or domain name of your PowerPBX server.
  • Dial *43 to run the echo test.

If the echo test instructions play back and you hear your own voice then you have successfully set up a SIP extension and verified that it is working properly.
