Imagine this harrowing experience; your Boss wanders into your cube and says…
“I thought you said switching to Jabber was going to save us licensing on all these phones this year! I just got our bill and it’s still gonna cost us jiggadollars for phones I know aren’t in use any more.”
You gulp and reply “It will, I promise! I … I’ll rearrange my priorities and get on that right away.”
Let’s solve this problem!
Get a list of all devices
Out of the box we build a list of devices that have been seen in the CDR records. This works great, but has one shortcoming – if a phone or device hasn’t participated in a single call in the period you have data for, then we’ll have no way of knowing about it so it just won’t show up anywhere.
We can fix this! If we “taught” the app what all devices you actually have by giving it a list of them, then we can easily see which ones are in that list but don’t show up in the data. If you followed the bouncing ball here, that’s the list of phones/devices that haven’t made a call in a long time, or maybe even “ever” made a call.
So what we need is a list of all devices in CallManager.
