Dialing-in from an H.323 Endpoint
Simple Dial-in Using the IP Card Address
In simple dial-in, the participant dials the IP address of the IP card installed in
the MCU, so no gatekeeper is required. The participant is routed to the
destination conference according to the participant’s IP address defined for
the participant in the conference.
Figure 2-4: H.323 Participant simple dial-in using the IP Card address
In this dial-in mode, the MGC Manager operator must manage the system
resources by distributing the participant connections between the cards. This
is done by giving the IP address of the appropriate H.323 card to each of the
participants.
Simple Dial-in Using the IP Card Alias
Participants can use the alias of the IP card installed in the MCU to dial-in. In
this mode, a gatekeeper is required in order to provide address translation and
routing to the IP module. When the participant enters the IP card alias, the call
is routed to the gatekeeper that forwards the call to the appropriate IP card
according to its table of aliases and IP addresses.
