Hi everybody, Quick question about call routing with PBX + Twilio. Flow is: • Incoming call hits the main PBX number • Based on the language selection, the call is routed to a specific Twilio phone number where the AI answers • If the AI needs to hand off to a human, it should transfer the call back to the PBX, so the PBX can route it to the correct internal extension Question: Does Retell support transferring a call back into a PBX in a way that allows the PBX to route it to a specific internal extension? Or is it only possible to transfer calls to full external phone numbers? If direct extension transfer is not supported: What would be the recommended setup on the PBX side? Would this require direct inward dialing (DID), routing rules, or another workaround?
