In addition to support as local IP Office extensions, J100 Series phones are also supported as Avaya Aura® extensions which, in rainy-day scenarios, can failover to the IP Office for basic call functions. Within the IP Office configuration these are referred to as 'centralized' extensions. This is called 'branch deployment'.

In this scenario, it is important to ensure that the centralized extensions do not start using the settings files intended for local extensions. This is done through the use of the GROUP setting on the phones:

• Natively IP Office extensions should be left with the default GROUP setting of 0.

• Centralized Avaya Aura extensions be configured with a GROUP setting between 1 and 5 (see below).

• Add GROUP Redirection to the Settings File:

  • If the system is using an auto-generated settings file: Add the NoUser source number BRANCH_PHONES_GROUP=X to the IP Office configuration, where X is the GROUP number between 1 and 5 that the centralized extensions should use. The NoUser source number adds the setting GET 46xxBranchsettings.txt to the IP Office system's auto-generated 46xxsettings.txt file.

  • If the system is using a static 46xxsettings.txt file: Manually add the settings to ensure that GROUP X phones are instructed to GET 46xxBranchsettings.txt.

• Add a 46xxBranchsettings.txt file to the IP Office or IP Office file server. Use that file to specify the settings for centralized extensions. This is covered in the IP Office branch deployment documentation.
