Registration Mode
Select the mode in which the proxy will direct the incoming SIP call to the MCU’s IP card that has resources to handle the call, based on the mode supported by the proxy. If all three methods are supported, select the required working method.
•Redirect – The conference registers with the proxy using the IP address of a specific IP card. The proxy directs the incoming call to the registered card. If the card has no available resources, the MCU returns to the proxy the IP address of the card that does have enough resources and the proxy redirects the incoming call to that IP card.
•Forking – Each IP card is registered in the proxy with all the conferences. The proxy directs the incoming call to all cards simultaneously. The MCU ensures that only the card that has enough resources answers the call.
•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.
