Update timeline

  1. investigating Nov 03, 2025, 05:59 PM UTC

    We have identified call connection failures specific to Toll Free destination lines owned by AT&T. At this time we have determined this to not be an Invoca specific issue and more broadly an AT&T issue. We have opened tickets with our downstream providers for awareness and are continuing to monitor the issue. Caller experience is long delays followed by a "number not in service" or "busy" message.

  2. identified Nov 03, 2025, 08:03 PM UTC

    We are continuing to monitor the issue as we have not seen a reduction in the failure rate to Toll Free destination lines owned by this carrier and will continue to provide updates as more information becomes available.

  3. resolved Nov 03, 2025, 10:30 PM UTC

    We have observed normal call behavior to all Toll-Free destination lines for the past hour, and all services have returned to full stability. We are marking this incident as closed.
