Extension Mobility Resiliency

Is it true that the EM service depends on the Publisher being available, and should only be installed on the Publisher? If EM is installed on a subscriber, will EM work if the Publisher is unavailable (and the URL for the EM service can be pointed at the new server)?

Re: Extension Mobility Resiliency

If PUB goes down EM wont work since it makes DB writes into SQL.

The main features and functions that require access to the publisher for write access include:

•Configuration additions, changes, and deletions

•Extension Mobility

•User speed dials

•Cisco CallManager User page options requiring the database

•Cisco CallManager software upgrades

•Call Forward All changes

•Message Waiting Indicator (MWI) state

Other services or applications might also be affected, and their ability to function without the publisher should be verified when deployed.
