It was the route selection. All outbound routes have a CID pattern to identify which extensions can use a route. Some extensions use one route with a specific outgoing CID, others use a different on.
When a call comes in on a trunk, the CID is set to that of the caller. When the ring group tries to call the external number, it uses that CID. Since all of the outgoing routes had CID patterns on it that would only match one of the extensions, no route could be selected.
I have now added an additional outgoing route with a pattern matching the external number and a CID pattern set to “XXXXXXXX.”. This will now be selected when an inbound route selects the external number.
Everything is working now. Thanks for helping me solve this.0
