Introduced in SIP Server version 8.1.101.57, Shared Call Appearance (SCA) enables a group of SIP phones to receive inbound calls directed to a single destination (shared line); that way, any phone from this group can answer the call, barge-in to the active call, or retrieve the call placed on hold.
The call flows in this section describe the functions and events related to SCA functionality:
- Inbound Call Alerting
- Inbound Call Answered
- Call Termination by a Non-shared Line Pone
- Outbound Call from SCA
- Hold/Retrieve
- Barge-in
