All affected phones are appearing back in our provisioning tenant. Users may need to reach out to Unified Communications to get the phones signed back in as needed, but the service is running as it should.

Unified Communications continues to work with the vendor on this issue. Service has been restored to most of the impacted phones. However, we have roughly 30 phones still suffering loss of service. We will continue to keep updating as we get more information

Unified Communications worked with vendors throughout the weekend and the vendor has identified some issues. We're starting to slowly see some phones in a status where we can work with them again.
