I just installed a Pantech modem on my router, and it or Verizon appear unable to support UCP. I tried using TCP on my wired connection, and the SIP phones are unable to register.
I unblocked the ports on my router. Is there anything I need to do on the FreePBX / Asterisk server to enable SIP traffic over TCP?
Yes, the extension is set to “All-TCP Primary”. There is a note to make sure the “SIP Asterisk Settings” are set correctly but I don’t see anything on that page to set. Any ideas?
When I put it in Advanced SIP Settings, I got an error message to do it on the Advanced Page. And it wasn’t there! I’ll try the conf file and see it that works!
