Call Forwarding Guides for Every Carrier

Updated · 4 min read

Step-by-step for RingCentral, Nextiva, Vonage, Verizon, AT&T, T-Mobile, and Google Voice.

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

  1. Log in to your RingCentral admin portal
  2. Go to Phone System → Extensions → select your user
  3. Click Call Handling & Forwarding
  4. Add a new forwarding number — 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"
  5. Enter your Call IQ number
  6. Set ring time before forward (recommended: 15–20 seconds)
  7. Save

Vonage Business

  1. Log in to Vonage admin portal
  2. Go to Extensions → select your number
  3. Click Call Forwarding tab
  4. Enable "Forward calls to another number"
  5. Enter your Call IQ number
  6. Choose forward condition: Always or When unanswered
  7. Save

Regular Cell Phone (Verizon, AT&T, T-Mobile)

⚠️ Note: These codes forward calls unconditionally — your phone won't ring, calls go straight to Call IQ. Consider using a separate business line or porting your number to Call IQ for more control.
