Deploying AE Services in high availability configuration

About this task

Use this procedure for active, standby, or N+1 redundancy configurations.

Procedure

  1. Configure the backup AE Services server (or servers) with the same dial plan as the active AE Services Server (or servers).
  2. On the Microsoft Communications Server, administer static routes for all active AE Services servers only.
  3. On Microsoft Office Live Communications Server, Office Communications Server, and Office Communications Server R2, specify each standby AE Services server as an authorized host on the Host Authorization tab. Make sure you select Throttle As Server and Treat As Authenticated check boxes.
  4. In the event that an active AE Services server is not available, edit the static route entry for that server, and point it to the IP address or DNS address of the backup server.

    All Microsoft Office Communicator clients periodically attempt to re-establish their sessions. As soon as this entry is updated, all INVITE messages are routed to the new active server, and new sessions is established with that server. If it is desired to move back to the primary server once it is back online, the administrator only needs to update the static route entry again, and all new sessions will be established with the restored server.
