SCA supports the IP phones barging in an active call. In addition, SCA has the call pull capability.
Call pull feature allows users to retrieve an existing call from another shared phone that is in
active or public hold status.
If the call is placed on public hold, the held call is available for any shared party to retrieve. If the
call is placed on private hold, the held call is only available for the hold party to retrieve. You
need to configure either the private hold soft key or a private hold DSS key before you place the
call on private hold.
