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
key before you place the call on private hold.
