Resolved. Between 8:06 and 8:39 AM ET, a subset of voice agent calls for one account failed to connect due to a bug introduced in a recent update. These caused affected calls to fail to start. The change was rolled back and verified, with normal call handling confirmed since 8:39 AM ET.

The issue has been identified. We are working on a fix for the issue.

We're actively investigating and will provide an update within 15 minutes.
