> during call setup asterisk tries ReINVITE to both peers, but fails because of the incompatible codecs (ulaw <> alaw). Afterwards, asterisk sends BYE to both peers and hangs up the channels.
> I can reproduce this on asterisk 1.8.13.0 and upwards. I have not tried lower versions but I suspect they are affected too.
> I would expect one of 2 things:
>    - Asterisk does not try reinvite at all (it knows that the codecs are incompatible)
>    - Asterisk tries reinvite, but keeps the channels up when it fails.
