Call Forwarding Guides for Every Carrier

Published · 4 min read

Step-by-step for RingCentral, Nextiva, Vonage, Verizon, AT&T, and more.

Quick Answer: Forwarding your calls to Call IQ takes 5–15 minutes. Here are the exact steps for every major carrier. No technical expertise required.

To use Call IQ, you have three options: port your number (free, takes 5–10 days), get a new number (instant), or forward calls from your existing carrier (5–15 minutes). This guide covers the third option.

RingCentral

  2. Go to Phone System → Extensions → select your user
  3. Click Call Handling & Forwarding
  4. Add a new forwarding number: +1 (YOUR_CALL_IQ_NUMBER)
  5. Set sequence: Ring your desk phone first, then forward to Call IQ after 15 seconds
  6. Save changes
  7. Test by calling your RingCentral number

Nextiva

  1. Log in to Nextiva admin portal
  2. Go to Users → select your extension
  3. Click Call Forwarding
  4. Enable "Always forward" or "Forward when unanswered"
