OT: 
I have a couple of asterisk boxen, and yes, I see that error from time
to time.
But still, in my opinion IAX2 is a nice protocol and it works great for
us.
Troubleshooting is not as hard as you think.
In my experience, audio issues are either codec related, or connectivity
related. If it's the connection you will see your IAX peers going
OFFLINE or UNREACHABLE a lot.
With SIP you have all this trouble with RTP and routers that dont
understand it etc.

I think they should go with the Tech their DID provider prefers.
That way you will get the best support from them if something goes
wrong.
