  Ensure frames are not written to dialed channel if ringback is requested
  
  When a single channel was dialed and there was media to be forwarded to the
  calling channel, the media was written without regard for ringback causing
  silence to be heard in some circumstances.  This regression was introduced
  when the meaning of "single" changed to mean only the number of channels
  dialed.
