Hey all. All the cool voice AI with Retell, VAPI, Eleven Labs is awesome BUT how does this work in the real world. ie how do you connect this to a business. Is there a VOIP system that integrates well with AI voice systems to existing business phone numbers. Do you divert to a voip number in TWILIO, is there another solution? I have tuned the voice AI, but the last mile is to connect to a real business. Love to hear some practical solutions for this.
