> A call is initiated and successfully reinvited to T.38.  Both ends are happily communicating.  Once the session timer runs out, Asterisk sends an invite but this invite changes the audio stream back to G.711.  It only does this through one channel, so we end up with the caller sending T.38 and the callee sending G.711.  Things spiral downhill from there.
> End result is faxes that take longer than the session timer are not able to complete.
