About This Manual
MultiVOIP models (MVP130-AV, MVP130-AV-FXS, MVP210-AV, MVP410-AV, & MVP810-AV) being used
in systems containing Avaya PBX units and controlled by Avaya TM Communication Manager software
differ only slightly from those being used in general voice-over-IP applications. Because this is so,
comprehensive information on the general setup of these MultiVOIP units can be found in the MultiVOIP
User Guide. However, certain MultiVOIP parameters are unique to operation in Communication Manager
systems. This manual describes these parameters.
Beyond general setup information (like Mechanical Installation, & Cabling, LED definitions, and other
general info which are presented in the MultiVOIP User Guide & Quick Start Guide), this software guide
presents all the information you need to configure your MultiVOIP for use in a Communication Manager
system. It presents information on the MultiVOIP software screens as well as the related Communication
Manager screens. The MultiVOIP User Guide remains valuable as a reference source.
MultiVOIPs in Avaya Communication Manager Systems
The Communication Manager build of the MultiVOIP software allows for use of MultiVOIP units in
conjunction with IP-equipped Avaya PBX units. These PBXs are equipped with H.323 gatekeeper
functionality and support endpoints such as IP phones and MultiVOIP gateways.
In addition to functioning as a gateway, the MultiVOIP also contains an integrated gatekeeper, except
MVP130 Models. This allows the MultiVOIP to serve as it’s own alternate gatekeeper should
Communication Manager be unavailable. When serving as an alternate gatekeeper, the MultiVOIP
processes registration and call routing for it’s local FXS/FXO/DID ports as well as local Avaya IP phones.
This is the MultiVOIP’s “gatekeeper survivability” mode.
Each MultiVOIP voice channel can be registered with a primary Communication Manager gatekeeper or
one of two optional alternate gatekeepers. The optional gatekeepers can be other Communication Manager
gatekeepers or the integrated MultiVOIP gatekeeper.
The diagram below shows a common function for the MultiVOIP unit within the Communication Manager
network: the MultiVOIP allows selected callers at a site remote from the Avaya PBX units to have access to
the PBX units and all of their extensions without tolls. Voice and fax calls are supported.
