I am attempting to setup a user (IP500 version 5.0 on both systems) to unconditionally forward their calls to an outside number using a PRI or a T1 (I have 2 systems one which has a full t1 and another has a partial PRI). When I call inbound on the either circuit and transfer to the extension the fowarding does not work. Is there something special that you need to configure to allow trunk to trunk transfer like you do on analog lines? My in-house test system which only has POTS lines with trunk transfer allowed works perfectly.
