Centralized voicemail options
IP Office systems deployed in Distributed, Mixed, or Centralized enterprise branch environments can be configured to use the following Centralized voicemail options. Stand-alone branches cannot use Centralized voicemail systems.
-
Avaya Aura Messaging — An IP Office system can be configured to use Avaya Aura® Messaging as its voicemail server when Session Manager is used as the core SIP router.
-
Modular Messaging — An IP Office system can be configured to use Modular Messaging as its voicemail server when Session Manager is used as the core SIP router.
-
CallPilot — An IP Office system deployed as a Distributed enterprise branch in a Avaya Communication Server 1000 branch environment can be configured to use Avaya CallPilot® as the voicemail system. In this deployment, the Distributed enterprise branch configuration includes Session Manager as part of the CS 1000 core. All users in this configuration are IP Office users.
When a central voicemail system is configured for the branch, the mailboxes of the branch users are on the central voicemail system. However, you still have the option to use the automated attendant of the IP Office local Embedded Voicemail or the call flows of a local Voicemail Pro, even though the embedded voicemail or Voicemail Pro are not used for the voicemail messages of the branch users. This configuration requires the use of Embedded Voicemail or Voicemail Pro port licenses. If the configuration requires more ports than the number of ports that are licensed and come with the IP Office system, additional port licenses are required.
When Messaging or Modular Messaging is used as the central voicemail system, IP Office users and Centralized users in Rainy day can leave and retrieve voicemail over the PSTN when the SM Lines are unavailable. DTMF digits are used to indicate a specific mailbox. Message Waiting Indication is not provided.
