UCaaS: Partial Inbound/Outbound Call Failures

Jun <var data-var='date'>30</var>, <var data-var='time'>02:45</var> CDT Resolved - This issue has been resolved. Jun <var data-var='date'>29</var>, <var data-var='time'>12:02</var> CDT Monitoring - Queued events are now processing concurrently, and the Realtime Call Center dashboard is recovering. Due to the backlog and out-of-sequence event processing during recovery, some dashboards may show incorrect call-waiting counts for today. We are working to correct these values where possible. Inbound and outbound calling remain unaffected. Calls continue to route and complete normally. Realtime dashboard activity is expected to normalize as event processing catches up. Daily dashboard statistics should display as usual starting tomorrow. Jun <var data-var='date'>29</var>, <var data-var='time'>11:33</var> CDT Identified - **Update: Realtime Call Center Dashboard Delays** We have identified the issue affecting the Realtime Call Center dashboard. A backend event processing service became degraded due to a high volume of invalid messages, which caused call center status updates to be delayed. A fix has been implemented, and queued events are now being processed. The dashboard may continue to show delayed or stale status information while the backlog clears. Inbound and outbound calling remain unaffected. Calls continue to route and complete normally. We expect the Realtime Call Center dashboard to be current within the next hour. Jun <var data-var='date'>29</var>, <var data-var='time'>10:24</var> CDT Investigating - We are currently investigating an issue affecting the Realtime Call Center dashboard. Call center event processing is delayed due to a backlog in the event processing service, which may cause dashboard status, agent state, and call activity updates to appear stale or delayed. Inbound and outbound calling are not impacted. Calls continue to route and complete normally. Our team is working to restore realtime event processing and will provide updates as we make progress.

May <var data-var='date'>29</var>, <var data-var='time'>18:27</var> CDT Resolved - The CNAM (Caller ID) service is fully functional without any performance constraints. May <var data-var='date'>29</var>, <var data-var='time'>16:02</var> CDT Monitoring - The Caller Id resolution is working as expected. We are monitoring for any further issues. May <var data-var='date'>29</var>, <var data-var='time'>13:41</var> CDT Identified - We have identified that our third-party CNAM provider is not responding within our required performance thresholds.
