        Investigating

        We are re-investigating a service interruption with Programmable Voice using Shaken/STIR. Signing and caller verification is impacted. This means outgoing phone calls are not reflecting the desired attestation. This does not impact calls from being placed. However, call answer rates may be impacted. We expect to provide another update in 1 hour or as soon as more information becomes available.
