For Gatekeeper functionality and interoperability see the Administrator’s Guide, Chapter 3, Defining a H.323 Network Service.

The MGC Manager determines the conference to which the participant is assigned according to the participant’s alias or IP address defined for the participant in the conference.

H.323 Advanced Dial-in

In this mode, the participant enters a dialing string that is the IP Network Service Prefix. Usually one IP Network Service is defined for all the IP cards installed in the MCU. The IP Network Service is registered with the gatekeeper using a prefix. (The prefix is defined using E.164 format, i.e. 0-9 digits, * and #.) This Network Service prefix is also entered in the IP Network Service Properties - H.323 dialog box. The Network Service prefix is given to the participants as the dial-in number. When the participants dial in, the call arrives at the gatekeeper. The gatekeeper locates the MCU and tries to allocate a port from the first free IP card. If the resource is available, the participant is connected and routed to the appropriate conference according to the participant’s IP address/Alias as defined in the Participant Properties dialog box. If the resource is unavailable on the first IP card, the system looks for the port on any of the available IP cards, and allocate the resources
