Setting Up Call Forwarding to Your Voice Agent
Configure your office phone to automatically forward unanswered or after-hours calls to your AI voice agent. This guide covers all major phone system types with step-by-step instructions.
Overview
Your AI voice agent can handle calls when:
- ✅ Your main line is busy
- ✅ You don’t answer within a few rings
- ✅ It’s outside business hours
- ✅ You’re on another call
How it works:
Customer calls your business → Rings your phone → If unanswered → Forwards to AI agent → AI handles the call
Before You Begin
You’ll need your Voice Agent’s phone number. Find it in your NZ Leads dashboard under Voice Agent → Phone Numbers.
Example: +1-909-555-0123
Identify your phone system type:
- Traditional Landline - Physical phone line from AT&T, Verizon, CenturyLink, etc.
- VoIP/Digital System - Internet-based phones like RingCentral, Nextiva, 8x8, Vonage Business
- Cell Phone - Using a mobile phone as your business line
Option A: Traditional Landline Setup
Simple Solution: Call Forwarding Service
Best for most landline users. Simple setup with minimal configuration.
Contact Your Phone Provider
Call your landline carrier:
- AT&T: 1-800-288-2020
- Verizon: 1-800-837-4966
- CenturyLink: 1-800-201-4099
- Other: Check your phone bill for support number
Request Call Forward Service
Ask for: “Call Forward Busy/No Answer” or “Call Forward No Answer”
Provide them with:
- Your voice agent’s phone number (e.g.,
+1-909-555-0123) - Ring duration before forwarding: 2-3 rings (10-12 seconds) for business hours
Activate the Service
The carrier will:
- Enable the service on your line
- Confirm forwarding rules
- Charge typically $3-8/month
Test It
- Call your business number from your cell phone
- Don’t answer - let it ring
- Verify the AI picks up after ~10 seconds
Limitations:
❌ Most landline providers only offer one forwarding rule
❌ You cannot set different timeouts for business hours vs. after hours
Advanced Solution: Google Voice for More Control
If you need different settings for business hours and after hours, use Google Voice as an intermediary.
Sign Up for Google Voice
- Go to voice.google.com
- Sign in with a Google account
- Get a new Google Voice number (free)
Add Your Landline as a Linked Number
- In Google Voice settings, click “Add another linked number”
- Enter your current landline number
- Verify it (Google will call to confirm)
Configure Forwarding Rules
- Go to Settings → Calls
- Set up forwarding rules:
- Business hours (9 AM - 6 PM): Ring landline for 3 rings (15 seconds) → Forward to AI agent
- After hours: Ring landline for 1 ring (5 seconds) → Forward to AI agent
- Your AI agent’s number goes in the “Forward to” field
Update Your Business Number
- Website: Change to your Google Voice number
- Marketing materials: Update to Google Voice number
- Google Business Profile: Update phone number
Why this works: Google Voice becomes your “public” number, and you control exactly how it routes to your landline and AI.
Cost: Free
Benefits: Time-based routing, voicemail transcription, call history
Option B: VoIP/Digital Phone System Setup
Most modern VoIP systems have built-in call routing. This is the easiest and most flexible option.

Let It Ring
Don’t answer - let it ring for the configured duration (usually 3-4 rings)
Verify AI Answers
- ✅ AI should pick up with your configured greeting
- ✅ Check that it sounds natural
- ✅ Have a short conversation (ask about services/pricing)
Check Call Log
- Go to NZ Leads Dashboard → Call Logs
- Find your test call
- Review transcript and recording
Test After Hours
Repeat the same test outside your business hours:
- AI should pick up faster (1-2 rings)
- Greeting should account for after-hours context (if configured)
Troubleshooting
AI Isn’t Picking Up
Check:
- ✅ Verify your AI agent status is “Active” in NZ Leads dashboard
- ✅ Confirm forwarding number is correct (check for typos)
- ✅ Make sure call forwarding is enabled on your phone system
- ✅ Wait 60 seconds for changes to propagate
Still not working?
Call your phone provider and verify forwarding rules are active.
Calls Forwarding Too Quickly
If the AI picks up before you have a chance to answer:
- Increase ring duration (4-5 rings instead of 2-3)
- Adjust in your call forwarding settings
Calls Forwarding Too Slowly
If customers hang up before the AI answers:
- Decrease ring duration (2 rings instead of 3-4)
- During business hours, 3 rings (15 seconds) is ideal
Call Forwarding Charges
Landline carriers: Usually $3-8/month for call forwarding
VoIP systems: Typically included
Cell phone carriers: Free, but may use minutes (verify with carrier)
Google Voice: Completely free
Wrong Greeting Playing
If your AI is using the wrong greeting:
- Go to Voice Agent → Edit Agent
- Update “Custom Greeting” field
- Save and wait 30 seconds for changes to apply
Recommended Settings
Based on thousands of service business calls:
| Time Period | Rings Before Forward | Seconds |
|---|---|---|
| Business Hours | 3-4 rings | 15-20 seconds |
| After Hours | 1-2 rings | 5-10 seconds |
| Lunch Break | 2 rings | 10 seconds |
| Weekends | 1 ring | 5 seconds |
Pro tip: During business hours, give yourself time to answer. After hours, forward quickly so customers don’t hang up.
