Issue when calling an ext that is not an ext

[[email protected]]

Hello. We're on V18 update 9 build 20. This is a fairly new install and we're having a strange issue. A user brought to my attention that when you dial a certain 4 digit extension that an outside service that belongs to the state which were in is where the call gets directed. This ext that is being dialed is not even an extension within our PBX at the moment so there's no forwarding happening. When i make the call myself while watching the Active calls i see that it go's out of one of our gateways as if i'm dialing an external number but i'm just dialing a 4 digit extension which corresponds to what we use for internal calls? Anyone experienced something like this before. I've looked through the outbound rules and gateway settings but don't see anything standing out. Thanks

Hi there.
If you run the report CALL REPORT, do you by any chance see any forwarding in there?
