For systems running in IP Office Subscription mode, the network's primary server is configured with details of a Customer Operations Manager (COM) service. Through that service, the primary server receives subscription entitlements for the users and IP Office services supported by the network.

COM users can see the status of the primary and other servers plus any alarms. COM can also support a range of other support features such as backup, restore, upgrade, remote access. For full details, refer to "Using Customer Operations Manager for IP Office Subscription Systems".
