This is crazy - I have two asterisk boxes one is 22.214.171.124.2(BOX A) and the other is 126.96.36.199.20(BOX B) connected by IAX2 trunk
If I reg one of my lines to (BOX B) it sounds great. IF I reg my line to BOX A and go through the IAX trunk to BOX B i hear breaking up of audio(mild) and it doesn’t sound as crisp. I know its not the network layout. when I test it’s after hours and I’m plugged in the same spot [color=#FF0000]closer to Box A[/color]. Box B is located over a VPN connection. But like I said if I reg my line to BOX B (not going through box A ) the audio sounds great. I’m think it’s something to do with the IAX trunk just not sure what to do next.
