I have installed a failover set up of Unity 5.0.1 using the following phases in a POC for upgrade:
Phase1 :Install a Unity 4.2.1 on OS 2003
Phase2 : Put the Back UP from the Live set p to the New server and Upgrade to 5.0.1
Phase3 : Install 5.0 on the Secondary Unity server
Phase4 : Configure failover between the servers
There is an issue with the MWI prompt. At the end of the installation I found that the MWI functioned only when primary was acitve.When I failover to secondary the MWI gave the message PENDING ON.
After making some changes in the configuration of the secondary voice mail ports ont the CCM (5.x) and recreating the integration I the MWI started functioning in the Failover mode (i.e. when secondary was active). But it stopped working for the Primary (i.e. when I failback).
Currently I have the MWI pending on for Primary.
I have already tired restatring the Exchange server as suggested in one of the topics.It did not work
Please point out the probable cause of the error and suggest a solution for the same?
