It seem that call diversion SIP 302 as been removed since MyPBX, as I found in this thread. I would like to be add again into P & S series since our telco operator work great with that and no way to allow "The Originator Caller ID" in the advanced trunk setup, since is not a diversion but a forward that generate a new call instead.
Call deflection (SIP code 302) work great in 3CX, in our case.
