   This is not a Vorco fault. Microsoft Teams is rejecting most inbound calls. We do see a small number of calls succeeding but large numbers being rejected. Microsoft support have advised us this is related to the global Teams outage earlier today and we will continue to follow up regularly for updates and update this incident as new information comes to hand.

   We're seeing calls succeeding now, although they may appear to ring for up to a minute as the Microsoft Teams service is still responding slowly and not accepting calls immediately.
