Hi, There are various ways of offering a 'Boss-Secretary' feature. The simplest, which we can call shared-line-monitor, would involve using the dialog event package (see http://www.ietf.org/proceedings/04aug/I-D/draft-ietf-sipping-dialog-pack age-04.txt) to show the status of the monitored (the boss's) line. The SIP service examples ID (http://www.ietf.org/internet-drafts/draft-ietf-sipping-service-examples -07.txt) takes this a step further in its 'Single Line Extension' example, by letting another user join a monitored call. A more popular requirement, in my experience, permits shared lines/AORs to be 'seized' by any one of the users that have registered against that AOR. Seizing a line effectively involves obtaining a mutex on the shared line resource so that no other user can make a call out on that instance of the AOR. This has a number of benefits when it comes to managing calls on the shared line. The ID 'Implementing Bridged Line Appearances Using Session Initiation Protocol' makes use of the dialog event package to provide the line seize feature (http://ietfreport.isoc.org/all-ids/draft-anil-sipping-bla-01.txt) - this draft has now expired, but an updated version should be out soon.
