Registration Mode
(cont.)
• Polling – Each IP card is registered in the proxy
with all the conferences and each card is
assigned a priority per conference. The proxy
directs the incoming call to one of the registered
cards. If the card does not have enough
resources, the call is rejected and the proxy
redirects the call to the next card according to the
card’s priority. Usually, the load is distributed
between the cards by registering the first
conference with the first card, the second with the
second card, and so on.

SIP Factories Select the conferencing types and methods to
register with the proxy.
In SIP conferencing, the Entry Queues, SIP
Factories, Meeting Rooms and conferences register
with the SIP proxy. The endpoint calls the Entry
Queue, Meeting Room or the conference directly and
not the card (as with H.323 conferencing, where the
cards are registered with the gatekeeper and the
dialing can be done directly to the card).
Registering all the conferences with the proxy loads
the proxy and the MCU as the registration is
refreshed constantly (every x seconds). Therefore, it
recommended to register only the Entry Queues and
SIP Factories, and define all the conferences and
Meeting Rooms as Entry Queue Access. All the
incoming calls are routed to the Entry Queue by the
proxy and from the Entry Queue to the conferences
by the MCU.
Reservations are not registered.
Note: To use SIP Factories, the Entry Queues & SIP
Factories check box must be selected. For more
information about SIP Factories, see the MGC
Manager User’s Guide, Volume II, Chapter 3, “SIP
Factories”.
