We have Cisco Unified Communications Manager 7.1 and we have used MS Exchange UM for voice mail. We are converting the first test users over to MS Exchange UM 2013 and there are a couple of oddities with which I'd like help.
1) The Message Waiting Light (MWI) is now coming on when someone leaves a message. Sounds like a good thing right? But here's the deal it never did work with UM 2007 and we assumed the reason was that the message was going to email. So it was kind of besides the point as most people just listen to the .wav file out of their Outlook. But not somehow the MWI is lighting when a new voice mail comes in. But the kicker is - if I go to CUCM Administration - Voice Mail/Message Waiting and click Find - there is clearly nothing configured in here. How is the MWI light getting triggered on my phone if no MWI extension has been defined??
2) At the initial cut-over to 2013 the MWI on my phone was on. I retried the voice mail from my phone and was able to interact with the 2013 UM IVR just fine. It told me I had four voice mails. When I listened to them they were very old - months old. It wasn't a big deal for me. I just told the robot "delete" "delete". And after that it's working just as I want. But.. if I deploy this to my users I'd rather not have their phone telling them they have a bunch of new voice mails that are way old.
Any thought as to what's going on here?? Thank you!
