Hi Michael,

The two first calls are terminated by the PBX.

It sends a STATUS message "Q.850: message not compatible with call state or 
message type non-existent or not implemented".

Maybe this is due to the "SETUP_ACKNOWLEDGE", though this is all standard ISDN 
signalling.

What brand is your PBX ?

Have you tried on another PBX ?
