Avaya IP Office Platform Guidelines Capacity
Capacity Planning Beyond 3000 Users
To provide a cost effective solution of more than 3000 users or 150 sites to larger customers, two IP Office Select systems may be linked together to support a total of 6000 users/extensions:
This construct may also be used when other per-solution capacities are exceeded, for example Avaya one-X® Portal users, hunt groups or Voicemail/recording channels.
You can create a group by linking two separate IP Office Select systems via IP Office lines to provide a single system view to users.
Each IP Office Server Edition system has its own Primary and Applications, and optional Secondary Server and Expansion Systems; each IP Office Server Edition system needs to be managed separately. The systems are set up through configuration to share a common dial plan and directory.
