[Asterisk-Users] canreinvite and transcoding

[Glenn Dalgliesh]

Does anyone know if it is possible to force a extension to not allow
transcoding? If you spec canreinvite=yes the cal may still transcoded if the
parties do not choose a the same code on each end. In my situation it is
better that the call fail than have it transcoded.

Also, I see some limited reference to canreinvite=update. Does this command
exist and if so what does it do.

Thanks
