If you remove a Mediation Server from service without first taking appropriate precautionary steps, you can significantly impact the availability of service, including causing active calls to be dropped. Before deactivating a Mediation Server, do the following, as appropriate:
- Deactivate the Mediation Server on the weekend or holiday, or
during other off-peak hours, but only after you have checked the
call logs to make sure nobody is using that particular gateway.
- Change routes on the Office Communications Server so that no
new calls are routed through the Mediation Server that is to be
deactivated, and then wait for all calls to hang up. This option is
riskier than the first option because midcall transfers and other
types of call routing might be broken if the routes have been
deleted.
- Do a combination of the first two options by changing routes on
the Office Communications Server during off-peak hours, but only
after all calls are completed.

| Deactivating a Mediation Server can result in the loss of data
and settings. Before you start the deactivation procedure in this
section, ensure that all data and settings have been backed up and
appropriate restoration procedures are in place. For details about
backing up data and settings, see Backup and Restoration in the
Operations documentation at
