We have an on-premises Cisco VOIP system (which I still do not anywhere near fully understand) and are trying to complete our migration from IP Communicator to Jabber. We have a switchboard system that uses Attendant Console and all works fine with IP Communicator. When a user tries to use Jabber as their phone and Attendant Console, AC reports an error message.
"Your extension #### is out of service. You will not be able to make or receive calls."
So far based on my searches I have attempted the following which have NOT fixed it:
- Associating the end user with the line on the Jabber device in CUCM.
- Giving the AXL user the Standard CCM Super Users permission in CUCM.
- Giving all application users control over the relevant Jabber device in CUCM.
CUCM System version: 14.0.1.13900-155
CUAC System Version: 12.0.5.10-13 Administration Version: 12.0.5.1823
PS: We also have a call queue system using Finesse and that is working normally with Jabber as far as I know, although users are still testing it with full adoption to come.
