Description
•
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.
Select the conferencing types and methods to
register with the proxy.
In SIP conferencing, the Entry Queues, 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
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.
Enter the frequency in which the system informs the
SIP proxy that it is active by re-sending the details of
all conference types to the server. If the various
conferences and Entry Queues do not register within
the defined time interval, the SIP server will not refer
calls to this conference/Entry Queue until it
re-registers. If timeout is set to 0, re-registration is
disabled.
The default value is 3600 seconds (60 minutes).
