Shared Call Appearance Signaling
A shared line is an address of record managed by a call server. The server allows multiple end
points to register locations against the address of record.
The handset supports shared call appearances (SCA) using the SUBSCRIBE-NOTIFY method
in the “SIP Specific Event Notification” framework (RFC 3265). The events used are:
 “call-info” for call appearance state notification
 “line-seize for the handset to ask to seize the line
