having configured a call forwarding ("forward all") on IP phone A to IP phone B (same partition)
will provide information on B's display that the call is being forwarded by phone A. So far, so good.
Unfortunately this information is not displayed for external calls for DN A. Instead ONLY external caller's number
is displayed on phone B without information that this call is redirected by phone A.
I played with Forwarded Call Information Display settings (caller name, caller number, redirected number, ...)
Have I missed something?
Thanks for any hint.
