Retell AI / PBX Expert

I am trying to use Retell AI to answer incoming phone calls and connect it with my existing pbx.

I already have prompts for the AI Agent but I don't know how to connect it to my pbx.

The goal is to have Retell AI Agent answer calls, take messages, book appointments/send SMS links to my calendar, or do a *WARM* Transfer to an existing extension on my pbx.

If you understand and are comfortable with this gig, reach out to me!
