Hi,
i have a PBX that communicates with a Call Manager 6.1 through a trunk QSIG (ECMA) in MGCP with a PRI E1 interface.
The router is a 2811.
the problem is that if i call from a PBX phone one IP phone unregistred that have a CF UNREGISTRED configured with external number, i hear busy tone.
the same situation with a CFA works.
thanks.

Is the forwarding calling search space set correctly on the call fwd unregistered entry? It is none by default, and set both internal and external.

It is there and the PBX phone rings, but the call drops after 4 secnonds on recovery on timer expiry for T3014 timer as I dont receive connect ack from the PBX.
however for call forward all,busy, no answer it works very normally.
