I’m providing an AI receptionist (Twilio number connected to Retell) for a client who uses RingCentral as their main phone system. Client requirements: - Customers must call the business’s RingCentral number (not my Twilio number) - AI should only handle missed calls - “Missed calls” include: No one answers after a set number of rings ; The line is busy - In those cases, the call should be forwarded to the AI (Twilio number) - After a missed call, the AI should: Call back or text the lead Problem I’m running into: RingCentral seems to want to forward all calls, but I only want calls to hit Twilio if: - No one answers after X rings, or - The line is busy What I’m trying to figure out: - Best way to detect a “missed call” or busy line in RingCentral and trigger Twilio - Whether this should be handled via: - RingCentral call handling rules (ring count / busy forwarding) - RingCentral → webhook → Twilio - Or a middleware tool (Make / Zapier / n8n) - Any proven setups others are using where AI acts as a fallback, not a replacement If anyone has implemented RingCentral → AI only on missed calls / busy, I’d really appreciate the guidance.

Quick question, I’m setting up AI voice agents for small businesses and want to keep it simple. How do you handle it when a business wants to keep their existing phone number? Do you forward it to your AI, or do you use a separate number? Any tips on avoiding call loops while letting the AI answer first and still allow a human transfer?

I’m trying to decide between two options for my email outreach setup. Option one is to purchase prewarmed emails that will be available in 21 days, but they come with a limited selection of domain names. Option two is to go with a done-for-you email setup, which costs $5 less per email but requires me to handle the warmup process myself — which can take about two weeks. I’m currently using Instantly.ai, but I’m open to suggestions for other reliable platforms or approaches. What would be the better long-term choice in terms of deliverability, cost, and flexibility?
