- postmortem May 01, 2026, 06:13 PM UTC
Following the successful completion of the scheduled cutover for Sinch, Bandwidth, and ThinQ to cCFS, two separate voice service issues were reported the morning of May 1, 2026. The first issue resulted in one-way audio and was caused by a routing issue between the Chicago Secondary SBC and cCFS. The routing issue was identified at approximately 06:05 MST and corrected by approximately 06:12 MST, restoring call audio. The second issue affected some inbound calls over Bandwidth and was determined to be related to SBC call policy settings that required adjustment following the cutover. The policy issue was identified at approximately 07:35 MST and resolved by approximately 07:45 MST. Resolution was confirmed through testing and partner ticket validation at approximately 07:48 MST.
