Bridged Call Appearance
A Domain Control station can have a bridged appearance(s) of its primary 
extension number appear at other stations. For bridging, event reports are 
provided based on the internal state of bridging parties with respect to the call. A 
call to the primary extension number alerts both the principal and the bridged 
appearance.Two or more “alerting” events are triggered, one “alerting” for the 
principal, and one “alerting” for each of the bridged appearances.
Two or more “connected” events may be triggered, if both the primary extension 
number and the bridged appearance(s) answer the call. When the principal or 
bridging user goes on-hook but the bridge itself does not drop from the call, no 
event report is sent but the state of that party changes from the connected state to 
the bridged state. When the principal or bridging user reconnects, another 
Connected Event Report is sent. A Drop Event Report is triggered for the principal 
and each bridged appearance when the entire bridge drops from the call.
Members that are not connected to the call while the call is connected to another 
bridge member are in the “bridged” state. When the only connected member of 
the bridge transitions to the held state, the state for all members of the bridge 
changes to the held state even if they were previously in the bridged state. There 
is no event sent to the bridged user association for this transition.
Both the principal and bridging users may be individually domain-controlled. Each 
receives appropriate events as applicable to the controlled station. However, 
event reporting for a member of the bridge in the held state is dependent on 
whether the transition was from the connected state or the bridged state.
Call Control requests work normally if invoked over the station domain, regardless 
of whether both the principal and bridging user(s) are on the connection. However, 
Third Party Selective Hold, Third Party Merge, Third Party Reconnect, and Third 
Party Selective Drop are not permitted on parties in the bridged state and may 
also be more restrictive if the principal of the bridge has an analog set or the 
exclusion option is in effect from a station associated with the bridge.
A Third Party Auto Dial or Third Party Make Call call always originates at the 
primary extension number of a user having a bridged appearance. For a call to 
originate at the bridged call appearance of a primary extension, that user must be 
off-hook at that bridged appearance at the time the request is received.
The Party ID Query only reports those members of the bridge in the connected 
state. If the entire bridge is in the held or alerting state, then only the principal is 
represented in the reply.
The Redirect Call capability is allowed either from the primary or the bridging user 
as long as the call is alerting. If successfully redirected, the alerting call will be 
dropped from both the primary and bridging user sets.
