  Improve our handling of T38 in the initial INVITE from a device.
  
  We now answer with matching media streams to what is requested. If an INVITE
  is received with both a T38 and RTP media stream this means we answer with both.
  For any outgoing calls created as a result of this inbound one no T38 is requested
  in the initial INVITE. Instead if we start receiving udptl packets we trigger a
  reinvite on the outbound side.
