in a UCM 8.5 cluster environment, which is the best way to configure the redundancy of Enterprise Parameter that handle the URL Services? Particularly, if the Publisher goes down, old phones like 7940 or 7960 should be able to reach the Services pointing to another server in the cluster.
We have made some tests inserting on the Device configuration the URL with the IP address of a Subscriber but it doesn't work.
7906, 7911, 7975 do not have this problem, also Extension Mobility works fine on them in terms of redundancy.
Anyone has some suggestion?
