Can anyone help please? I've run out of things I know to try, can't seem to figure this one out and it's really the only thing that isn't working and they use it heavily.
New development, if I set everything back to defaults and just add:
To the end of the config file, and then in the public zone I add a traffic selector to allow ALL traffic from the remote IP, everything works. So apparently there are some ports that need to be forwarded other than the SIP port. I had to forward UDP 10000-15000 to get audio to work already. Does anyone know what ports I need to forward in order for the Messages and Call Pickup to work??
From a packet trap I can see that when the messages button or Pickup button are pressed, it is trying to use Port 5060. I even manually changed SipUdpPort to 25125 and SipTransport to UDP on the phone settings manually. The packet trap shows the source port is 25125, but the destination gets changed to 5060?? Since we don't have 5060 approved through the firewall, it's not going through. So why is it trying to send the signaling to 5060? What am I missing here??
Figured it out!
All I had to do was use the default configuration, make the changes noted in the remote phone setup guide and then add 2 more lines and everything works.
So I added:
Then I went back and added:
That forced it to use port 25125 for all outbound communication. Messages, Park, and Pickup all work flawlessly.
