> Asterisk keeps trying to transcode video into audio.
> Im trying to pass a call from peer 1, to peer 2.
> peer 1 has following enabled.
> disallow = all
> allow = g722,ulaw,alaw,h264
> peer 2 has the following enabled
> disallow = all
> allow = speex,ulaw,alaw,h264
> Unfortunately, i have to have g722 enabled on peer 1, and disabled on peer 2.
> Now i would have a successfull call if either, asterisk transcoded the g722 to ulaw or speex, or if asterisk negotiated the whole call to run on ulaw.
> instead i get these messages
