Really annoying intermittent problem dialing out.

[VOIPoTim]

More information:

I've been doing some troubleshooting, and it appears that some of the trouble comes with whether or not certain media gateways accept the G722u codec. When I attempt to call my mobile phone (only allowing g.722u), I get an error indicating that my requested CODEC was not accepted.

I *think* that this issue will resolve if Voipo will be willing to proxy the audio for my calls. OTOH, I do not know what new issues doing so will bring up (aside from more load on their system and possible latency in my calls). I've floated the suggestion to Support - we'll see what they have to say.

That could definitely be it. Some of our vendors only support G.711.

Oops--I meant G711u, not G722u. The problem I'm having is that at least one of the media gateways my calls connect to does not accept G.711u but seems to require G.729 instead. I configured my trunk (briefly) to use ONLY G.729, and calls to my mobile phone worked, but then calls to several other numbers failed (which was expected behavior). Allowing both CODECs seemed to cause a 'battle of the codecs' based on my Asterisk log, and although the call stayed connected, no audio was transmitted. (I included a snippet of my logs in my ticket.)

Is it possible that there are some 'rogue gateways' that are causing this intermittent problem for other users?

The only thing I could think of would be peering. All the primary trunks are def 711 enabled. Can you send me some numbers you've seen this message on so I can see how they are routing out? If already in ticket, a ticket number is fine.

The numbers are listed in this ticket: RHG-145807.

This issue has only started occurring within the last few weeks (at most) for me. There are a few call reference IDs in the ticket that should help you see what's going on, too.

Thanks for checking on this!
