MS Teams & WebEx Calling App - 'Failed to load voicemail list'

[jim.stengle]

Anyone seeing issues with the WebEx Calling App in MS Teams not displaying voicemails or recent calls?

We get an alert saying 'Failed to load voicemail list' and no recent calls. 

This looks to have started after the update to version 2.1 which was installed last week.

The WebEx client does show voicemails and recent calls itself, just not the app in MS Teams.

Anyone resolve this issue?

The error message disappeared, now a new, more elegant message appears. Call history keeps crashing.

Hi Jim and those who are experience the similar issue, can you please let me know which version of Unified CM and CUC you are running?

Hi:

Cisco Webex APP is register Unity service ok, but the voicemail error appears in MSTeams and recent calls do not appear updated. I linked the line with the user in the CUCM, but it remains the same behave.

Hello everyone.

I have the same problem. I have some users who do not have voicemail and they get this message. I have deactivated the Unity of the CUCM Service Profile and I still get the same message. I also removed the Unity DN profile. The problem persists
