two concurrent calls per registration (line). This is an artificial limit and will be
expanded in the future.
3.1.20 Shared Call Appearances
Calls and lines on multiple phones can be logically related to each other. A call that is
active on one phone will be presented visually to phones which share that call appear-
ance. Mutual exclusion features emulate traditional PBX or key system privacy for
shared calls. Incoming calls can be presented to multiple phones simultaneously. This
feature is dependent on support from a SIP server which binds the appearances
together logically and looks after the necessary state notifications and performs an
access control function. For more information, see 5.2.4 Shared Call Appearance Sig-
naling on page 139.
