I would guess the remote server only allows calls to come in on channel 
1.  Thats why it requests a channel change to 1 when the call is setup.  
I think that in the call SETUP message Asterisk requests channel 23 but 
the remote server denies that channel and instead asks for a move to 
channel 1.  You will need to check up on the Altiware config.
