We have identified the issue as a problem with the messaging coming to us from Microsoft. 20 seconds after the call is answered, Microsoft end the call. We have reported this to Microsoft and await response. This is not a VIA related issue, but a Teams related issue and so will impact other users globally. For this reason, it's likely we will soon see an update on the Microsoft status page. A further update will be posted from VIA at 10:30 or if sooner, as it becomes available.

We are currently investigating an issue where by inbound calls made to Teams are suffering early termination. We will update further as soon as information becomes available.
