A dead-simple way to build a call-routing voice agent (free templates)

🔥

I’ve built and sold over $30,000 worth of voice agents and automated 50,000+ calls — here’s how I set up reliable call routing in Retell without overthinking it.

I keep seeing builders struggle with multi-department routing.

Here’s the small framework that solves it:

What it does

Detects caller intent (sales, support, billing, or “transfer to human”)
Routes the call to the right department
Optional: routes to the exact staff member the caller asks for
Handles fallback if the transfer fails

How it works

Add a routing logic section in the prompt with simple wording
List out phrases that map to each department
Add phone numbers for each department or staff member
Include a “please hold while I transfer you” node before handoff

Why it works

The AI gets clear examples → fewer misroutes
Callers reach the right person faster
No more one-number bottlenecks
Easy to scale from 1 rep to 50+ staff members

I've also got these 3 templates (single transfer, multi-department, and staff-level routing) available as well so feel free to send me a DM, happy to share them!
