Hey, we're experiencing a weird problem with Asterisk 1.8.13.1 (1:1.8.13.1~dfsg1-3+deb7). Calls that leave and enter Asterisk via a PBX (sipgate.de) work perfectly fine, almost 100% of the time.
However, calls that are routed to sipgate.de, which then routes the call back to our Asterisk instance are "silent" most of the time. What I mean with that is that even though RTP traffic flows, neither side can hear anything from the other. This problem happens when people at site A dial someone at site B using the number provided by sipgate.de, but also if people call each other within a site through the external number, i.e. if I dial 089-1234567-100 from 089-1234567-200. I have not been able to reproduce this problem with purely internal calls, i.e. calling ext. 100 directly, so I am assuming there's a problem due to sipgate's involvement. However, as far as I understand, once the call is established (and both parties' phones suggest that), the traffic flows only via Asterisk (directmedia = update,nonat), so the problem is likely to be found there, no? Before I shower you with debug logs and traces, I am wondering if this sounds familiar to anyone…?
