Retell AI

Yes  I can help with this.
Retell (through Twilio) can only transfer calls to full phone numbers, not directly to PBX internal extensions. The usual workaround is to have the PBX expose routing numbers (DIDs or equivalent) that map to specific extensions or queues. When the AI hands off, the call is sent back to one of those numbers and the PBX handles the internal routing as normal. This is a standard and reliable setup, and I can help you design it end-to-end if needed.
