We have 3 IAX2 in trunks and one out IAX2 on TrixboxCE 2.6.1.1 everything works fine. But there is a problem with with phone calls from mobile networks. The call itself is established (it rings phones in the office) but here is no audio on both sides, ... although sometimes the call gets connected with no problem (approximately 2 out of 10 times).
When we call the mobile number back - it works. No issues with calls from land lines.
I used Wireshark to analyse network traffic on Trixbox's Ethernet interface while making a few test calls. That way I wanted to exclude Asterisk's influence. IAX streams seems to me fine - I could not see anything unusual except, in 'faulty' calls - there was no audio signal comming in - outgoing audio was ok (Wireshark could reconstruct it as audio streams but no sound from provider's side was present).
thanks for any ideas
