Something may be off in your MBX networking numbering plan. pgm 320-321 If the issue were inside the Summit it would play a recording saying invalid number.

First thing to do however is to check MBX pgm 179 and make sure you have trunk to trunk enable programmed to allow transfered calls from the incoming co group to outbound ip line group.
