We're seeing occasional one way audio issues for international calls going out to one of several carriers. On roughly 2 out of 5 calls outbound, there is no audio on the the calling party's side, however the called party indicates they can hear the calling party perfectly well. NAT is not involved anywhere on our side. Sniffing the traffic shows the rtp stream tries to start, coming in from the carrier, but then stops, which is probably why there's no audio on the calling party's side. There is however, rtp going out from us to the carrier, which is probably why the called party hears the calling party OK.
I enabled proxy_media=true and that seems to have fixed the problem (or the problem coincidentally stopped), so now I'm beginning to wonder if we're hitting any of the goofy Sonus bugs described here ... http://wiki.freeswitch.org/wiki/RTP_Issues I know my carrier uses a Cisco, but I also know their routes are transit, not direct routes, so I have no idea what other softswitches the rtp is going through before it finally hits the PSTN in whatever country is being called. Is there anyway to know if there's a Sonus in the media stream somewhere? Do the Cisco's do anything goofy that I need to be aware of as well? I can turn off proxy_media and run a pcapsipdump if that will help? As a side note, we have absolutely no problem terminating domestic calls via any of our domestic carriers/CLECs. This problem seems to be only plagued with International calling.
