Figure 1. MultiVOIP in Avaya Communication Manager System

The MVP810-AV shown in the diagram on the previous page functions as a gateway registered to one of the Communication Managers in the IP network. The MVP810-AV provides survivable calling between the IP Phones, stations (FXS) and trunk (FXO/DID) ports at the remote site should the WAN link go down.

The MultiVOIP will not serve as a survivable gatekeeper for IP phones on the other side of the wan link.

If the WAN link goes down, the MultiVOIP will try to register six times with the Primary Communication Manager Gatekeeper at 3-second intervals. If the Primary gatekeeper does not respond, the MultiVOIP will try to register with the Alternate #1 Communication Manager Gatekeeper six times at 3-second intervals. If the alternate #1 gatekeeper does not respond, the MultiVOIP will register with the Alternate #2 gatekeeper, which is the integrated MultiVOIP gatekeeper. If the MultiVOIP registers to its own gatekeeper, this is gatekeeper survivability mode where the MultiVOIP will process registration and call routing for its local FXS/FXO/DID ports as well as local Avaya IP phones.

While in gatekeeper survivability mode, the MultiVOIP checks for the availability of the primary Communication Manager gatekeeper every 3-minutes. The MultiVOIP will re-register and discontinue its survivability mode automatically when the primary Communication Manager gatekeeper becomes available. Any calls that were established during the "survivable mode" which are still active while the MultiVOIP gateway returns to "subtending mode" to the CM gatekeeper, shall be preserved by the MultiVOIP gatekeeper. When these calls become inactive (idle), the MultiVOIP gatekeeper shall force these endpoints to unregister with the MultiVOIP gatekeeper and re-register with the CM gatekeeper.

If the MultiVOIP is not configured as an alternate gatekeeper, and none of the Primary, Alternate #1, or Alternate #2 CM gatekeepers respond, the MultiVOIP will enter gateway survivable mode (if enabled) and will process calls according to it’s inbound and outbound phone books. In gateway survivable mode, the MultiVOIP will check for the availability of the primary Communication Manager gatekeeper according to the Switching Time Interval programmed into the Communication Manager Parameters screen of the MultiVOIP configuration. The MultiVOIP will exit gateway survivability mode if it is able to register with the Primary CM gatekeeper. Gateway survivability mode is enabled by checking the “Enable Survivability Mode” checkbox in the Communication Manager Parameters screen. If IP phone survivability is required, you must enable gatekeeper survivability mode instead by configuring the MultiVOIP as one of the alternate #1 or alternate #2 gatekeepers.
