Call disconnected within a minute if 2 Webex App desktop clients connected to Calling in Webex Teams (Unified CM)

I have Webex Teams / New Webex App (Version: 40.12.0.17322) installed on 2 PCs and yesterday I inadvertently had both of the Apps running and logged into Calling (Unified CM). I found that any calls would disconnect within a minute whilst this was the case. After making sure that I only had one of the clients logged in I have not seen the behaviour repeated and I had not noticed this behaviour with previous versions of the app, although I cannot say for certain that I'd had multiple desktop clients logged into Calling (Unified CM) before. Can anyone ese verify this behaviour?

From my understanding you can only have 1 phone registered per end user using the Unified CM option. I have Jabber and WebEx Teams and I cannot have the phone registered on both devices on the same. I also tried having the phone registered on my laptop and on my VDI but as soon as I enable it on one side the other side automatically disconnects. I never got it to work on two devices simultaneously, unless its a laptop & mobile since they use different ucm profiles.

We have UCM setup using our ORG domain and Std Jabber User UC Manager profile (CSF). What is the need to have it registered to 2 separate devices at the same time?

There is no need, as stated this scenario arose inadvertently. But it happened and the resultant call dropping behaviour is a problem, it took me a while to realise what had occurred. I can't be the only person who has more than one PC with Webex app installed on it that might all be running simultaneously (e.g. I have an office PC, a home PC and a laptop).

The calls shouldn't be dropping regardless how many Webex apps you have as only one should be UCM-registered at a time from desktop. It would be best to log a case with Cisco TAC for that.
