h263 listed then it would work out of the door, but if the call was
setup without the codec, then a second invite came down the pipe to
asterisk with the new codec (h263) asterisk would pretend to
renegotiate but never passed h263.

Try setting only one video codec.

You must use a late VIDCAPS to get any usable video support from
Asterisk.
VIDCAPS adds important ability to handle SDP properly in the call
setup.

Subject: [Asterisk-video] h263 blackholed.
I'm trying to get asterisk to proxy h263 for a video call, but not
having
any luck. I have posted a full call trace here:
<a class="moz-txt-link-freetext" href="http://pastebin.com/d330aecb5">http://pastebin.com/d330aecb5</a>
While watching a full packet dump on the asterisk node, I can see the
h263 coming in from the clients, but it never leaves (asterisk never
originates 1 h263 packet). You can see on line 123 of the pastebin
that the
calls get setup without video but then h263 is renegotiated on line
456.
The second end point sets up h263 on line 313. I'm
pretty lost as to how I can get asterisk to play nice. This is
Asterisk 1.4.18.1
I just was able to test, and if the call sets up (the initial invite
contains) with h263, and isn't done with a re-invite at a later time
then it
works fine.
my sip conf looks like the following:
[general]
type=friend
host=dynamic
context=incoming
srvlookup=yes
canreinvite=no
videosupport=yes
qualify=yes
nat=yes
host=dynamic ; This device registers with us
disallow=all ;better for custom-tunning codec selection allow=ulaw
allow=alaw
allow=h263 ; H.263 is our video codec
allow=h263p ; H.263p is the enhanced video codec
dtmfmode=rfc2833 ; inband is not supported in compressed codecs like
gsm, so
we better set it to rfc2833
