Bulk Administration - Directory Number Voicemail Profile

[Robert Lake]

I am tryingg to figure out a way to bulk change the voicemail profile for a random sampling of extensions in Cisco Unified Communications Manager version 8.5. I know you can do this if there is some sort of unifiing feature between the extensions like Route Pattern, Line Description, CSS, etc. but I don't have that unifing feature because they are truly random.

I tried doing a phone update from custom file (extensions) and then changing the CSS(Phone) to something unique to the phones that I want to update the lines on. I then went to Phones > Add/Update Lines and queried that CSS(Phone) that I changed those phones to. But, when I do that if some of the phones had multiple extensions on them those extensions show up as well in the query...

Is there a better way to update the voicemail profile on just the extensions that I want to do it on?

Background:

We are moving to a differnent voicemail system but we have to do it in batches. Due to the fact that we are cutting over departments so I will only have the extension available to me to do the update.

You could move phones you wanted to up to new Device Pools, then update the lines in those device pools if you wanted to the new VM profile.   Otherwise, export all the phones details, then delete the columns you are not going to use, but are required.  (MAC, LINE, PT, etc).   Change the vm profile and then upload, update, and you are done.   The device pool is a little easier because it can be done all through CUCM GUI interface.  But you need to figure which phones are moving to the new vm system.  If you can move them to a temp DP, you can move them back later to the normal DP after hours.   You are basically just using the DP to help sort phones/lines out to do updates.
