8x8 engineers continue to work towards resolution of the issue. As a mitigation step, one specific UK outbound carrier has been removed from the rotation for UK mobile prefixes, routing calls through alternate carriers and now these calls are having the Block Caller ID option working correctly. We will continue to provide updates as they become available and we apologize for the inconvenience.

We continue our efforts to resolve the issue where users are experiencing the "Block Caller ID" functionality failing to suppress their phone numbers on outbound calls. Calls themselves continue to complete successfully and no other functionality is impacted. Investigations show that the Privacy ID property is missing on affected calls, causing the caller's number to be presented despite the block setting being enabled. This is being corrected by applying database-level changes with an ETA of 1-2 hours. As a continued mitigation the affected UK outbound carrier remains removed from rotation for UK mobile prefixes, with traffic routed through alternate carriers. We will continue to provide updates as they become available and we apologize for the inconvenience.
