Description:I have 2 SIP peers set up in this way
[peer1]
type=friend
username=peer1
secret=xxx
dtmfmode=rfc2833
restrictid=no
host=dynamic
mailbox=7725
pickupgroup=1
callgroup=1
context=NoRestrict
callerid=Jan <7725>
directmedia=yes
qualify=yes
disallow=all
allow=ulaw

[peer2]
type=friend
username=peer2
secret=xxx
dtmfmode=rfc2833
restrictid=no
host=dynamic
mailbox=7724
pickupgroup=1
callgroup=1
context=NoRestrict
callerid=Joris <7724>
directmedia=yes
qualify=yes
disallow=all
allow=alaw

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.

Please attach an Asterisk VERBOSE and DEBUG log of level 5, plus a SIP and RTP packet trace for a call demonstrating the problem.

Please attach them as separate file and not inline.
