   Starting at ~1:00 UTC, calls to a portion of phone numbers imported into the ElevenLabs Agent Platform are failing. We are currently working to isolate the root cause and restore full functionality.

   Calls should be back to normal for the EU and India residencies. The US residency may still experience some downtime, but our team is working to resolve the issue. In the meantime, the immediate workaround is to remove the affected number and re-add it, if possible.
