You can deploy IP Office as an enterprise branch to provide a communications solution that is adaptable to meet the growing needs of an enterprise branch network while providing investment protection of the installed hardware platform and phones. You can implement an IP Office enterprise branch on an IP Office Standard Mode, Essential, or Preferred system. The IP Office system can be installed as an independent, standalone branch, or be connected to the Avaya Aura® network and migrated to a Distributed, Centralized, or Mixed enterprise branch to provide specific features and applications to meet the needs of individual employees in each branch location.

In addition to centralized SIP endpoints or centralized analog devices configured as ATA, IP Office can concurrently support other IP and TDM endpoints for a community of Centralized users and IP Office users in the same branch. Ideal for enterprises wanting applications deployed in customer data centers or in the branch, an IP Office Branch can effectively deliver a range of communication tools without complex infrastructure and administration.

For more information on how to add Centralized users to an IP Office enterprise branch, see Administering Centralized Users for an IP Office™ Platform Enterprise Branch

IP Office is also supported in an Avaya Communication Server 1000 (CS 1000) branch environment. Only the Distributed enterprise branch option is supported. IP Office can be deployed as a new branch in an existing CS 1000 configuration with the addition of Avaya Aura® Session Manager to which IP Office connects through the SM Line for branch connectivity. Providing phone investment protection, IP Office can also be deployed as a replacement for Business Communications Manager (BCM) or Norstar in a branch office and connect to CS 1000 through Avaya Aura® Session Manager. IP Office cannot operate as a survivable gateway to CS 1000 endpoints as similar to Survivable Remote Gateway (SRG).

Integration of IP Office with CS 1000 is provided in a separate document. See Deploying Avaya IP Office™ as a Distributed Enterprise Branch in a Communication Server 1000 Environment with Avaya Aura® Session Manager.
