The issue has been resolved.
A configuration inconsistency introduced during the Call Queue migration to the new 3AZ infrastructure was identified and corrected without service disruption. The correction has been applied across the affected infrastructure, and Call Queue services are now operating normally.

We are currently investigating an issue affecting some Rainbow Hub customers using Alphalink SIP trunks.
Calls routed through Call Queues may connect without audio or without a ringback tone. Direct calls appear to be working normally.
As a temporary workaround, customers can replace the affected Call Queue with a standard Hunt Group.
Our technical teams are actively investigating the issue. Further updates will be provided as soon as more information is available.
