I guess it mostly depends on the Polycom device. For instance, it's a big difference if the call is transferred using blind or supervised transfer. You will probably need to collect the SIP traffic, and check what actually happens when doing this scenario.

Me I want that he see always caller ID of A. I tried to set "ignore_display_updates=true" in this case B see just C's caller ID when his is ringing and when he answer. There is any way to fix this issue? I am thinking about to set "effective_caller_id_number={$origination_caller_id_number}" but I am not sure if this will work. !DSPAM:4fba049932768390320688!
