Bug #3511
closedosmo-mgw does not forward RTP packets anymore
100%
Description
The MGW that is located next to the BTS seems not to forward any RTP packets. There are RTP packets comming from the BTS, but none of them get forwarded. The MGCP negotiation looks correct on the first look. All the ports match up and the circuit seems to be closed.
Attached one finds the configuration files, a trace and a map of the RTP traffic I worked out.

Apparently the reason for the fault is in the following change: Ie51cc86e90ffeca5b66bcb8f6db0d389241abe57. The client can now only create connections in MGCP_CONN_RECV_ONLY, which explains the behavior.

The problem should now be fixed, see also:

Hmm, I tested the patch and was routing voice calls with it all the time.
I see now that the patch did indeed cause this conn_mode change, my bad, but I'm still wondering:
shouldn't the MGCP messages indicate explicitly the receive/send mode?
