MGC Manager User’s Guide - Volume I
4-91
In simple dial-in, the MGC Manager operator must manage the system
resources by giving the appropriate IP address of the IP card to each of the
participants.
Simple Dial-In Settings (With Gatekeeper)
When using an H.323 alias to dial in to the MCU, a gatekeeper is required to
provide address translation and routing to the IP card. When the participant
connects to the conference, the participant enters the alias of the IP card as the
dialing string. The Gatekeeper routes the call to the appropriate IP card
according to the dialed alias. MGC Manager determines the conference to
which the participant is assigned according to the participant’s defined alias
or IP address. The aliases for the participant and the card must be defined in
the E.164 format, that is, using digits 0-9, * and #.
Figure 4-6: H.323 Participant Simple Dial-in (with Gatekeeper)
In this mode, resource sharing between IP cards is unavailable. If eleven ports
are taken by currently defined participants, it will be impossible to add a twelfth
participant who requires two ports, even if another card has enough ports to
allocate to that participant.
