Any IP phone can be used to originate or receive calls on the shared line. An incoming call can
be presented to multiple phones simultaneously. The incoming call can be answered on any IP

phones that share the call appearance.
IP phones support SCA using a SUBSCRIBE/NOTIFY mechanism as specified in
events used are:
"call-info" for call appearance state notification

"line-seize" for the IP phone to ask to seize the line

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
