Is anyone successfully using CallCentric without STUN, per the recommendation of CallCentric? I have had a support incident open with them for 3 days and we cannot find the issue. Here are the symptoms since STUN was disabled and I have gone to their recommended "user agent" configuration. I cannot dial out...I have an outbound rule configured with their default recommended settings. If I dial their test number, 17771234567, it rings (with the 3cx SoftPhone) and rings and rings but never shows up with CallCentric as an outbound call. If I dial other US numbers I will either get the same result as above or I'll get a 'Destination Not Found' error message. I receive inbound calls just fine but the problem is I can hear the caller but they cannot hear me. Internal calls between extensions work just fine. Any ideas?
