I tried all the suggestions posted so far without any luck. Here is the server log of a failed called. Extension 103 is the originator station on the 3CX system directly and is calling remote extension 101 (PAP2 ATA) located on a different network. Does anyone know what error code 401 - Unauthorized/Invite from 207.164.79.1:55290 means in terms of adapter configuration ?
