Transfer to Internal Number on SIP Trunk

I have successfully configured the AI Voice agent to make outbound calls and receive inbound calls to/from external numbers through the SIP Trunk.

I would also like the AI Agent to be able to call/transfer calls to internal numbers on the SIP Trunk PBX.

When transferring calls using the transfer call tool. If I use the SIP Trunk number and extension, it goes to the main entry point to the PBX and the extension is ignored. If I use just the extension number as a phone number, it uses that as if it is an external number and the call fails.

Is there some additional configuration I should be aware of to route AI Agent transfer calls to internal numbers on my PBX (VoIPline)?

I've contacted my PBX provider and they indicated they didn't see a request to transfer the call, so it seems to be coming in as a new call?

From their support: "According to the logs, we can see the call was answered by the SIP Trunk, but we didn't see any evidence of a call transfer"
