Conference on Demand (COD)
This feature allows you to bring multiple endpoints together in a
videoconference on an unscheduled basis. With Conference on
Demand, users can place multipoint video calls to remote
participants by only using their names and/or the numbers that
correspond to those remote locations. Users don’t need to save the
meeting name before making the meeting call.
Note
Release 5.0 of PathNavigator software, which supports ad-hoc
multipoint videoconferencing, is required for Conference on
Demand (COD) to work on your system.
Implementation of Conference on Demand
Users who want to use COD using sites from their Global Address
Book (GAB) that have both ISDN and IP numbers must decide
whether the number they are adding for that site is ISDN or IP.
Users who want to use COD using GAB sites that are ISDN numbers
must have their MGC located in the same country code and same
area code as their system. Otherwise, the numbers sent to the MGC
to dial the far endpoints in the conference may not be dialed
correctly. The Global Address Book normalizes global numbers to
the endpoints for that endpoints location.
The endpoint that placed the COD call cannot add a site that
dropped out of the call. All calls have to be dropped and the COD
needs to be initiated again. At this point, there is limited feedback
information available to the user who placed a COD call as to
whether the MGC has enough ports to complete the call.
There is limited feedback information available to the user who
places the COD call as to why any site in the conference failed to
connect to the MGC.
