Call Forwarding Setup

Learn how to set up call forwarding on your WhatSnap Android SMS device to route calls to Twilio, LeadConnector, or other numbers.

Call forwarding allows you to redirect incoming calls from your WhatSnap Android SMS device to another phone number—such as a Twilio number, LeadConnector number, or your main business line. This enables you to integrate voice calls into GoHighLevel while using WhatSnap for SMS.

Use Case: Forward calls from your WhatSnap SMS-only device to a number with full GHL calling features, while keeping your WhatSnap number for SMS messaging.

Instead of forwarding all calls, you can use conditional forwarding:

Forward When Busy:

Forward When Unanswered:

  • Rings on device first

  • If not answered within X rings, forwards

  • Good balance between direct access and backup

Forward When Unreachable:

  • Only forwards if device is off or out of range

  • Ensures calls aren't lost to voicemail

  • Device handles calls when available

Troubleshooting Call Forwarding

Common Issues

Call Forwarding Option Not Available in Settings

Possible Causes:

  • Carrier doesn't support device-level call forwarding

  • SIM card or account restrictions

  • Device software limitations

Solutions:

  1. Use Method 1 (carrier-level forwarding) instead

  2. Contact carrier to enable call forwarding service

  3. Check if your plan includes call forwarding

  4. Try using carrier codes: *72 + number + Call

Forwarding Works But Charges Are High

Possible Causes:

  • Forwarding counts as two separate calls

  • Forwarding to international number

  • Plan doesn't include forwarding minutes

Solutions:

  1. Contact carrier about forwarding costs

  2. Upgrade to plan with included forwarding

  3. Forward to local number instead of international

  4. Use VoIP alternatives to reduce costs

  5. Consider using LeadConnector/Twilio instead of forwarding

Forwarded Calls Go Straight to Voicemail

Possible Causes:

  • Forwarding destination number is offline

  • Poor signal at forwarding destination

  • Destination number blocked your number

  • Carrier network issues

Solutions:

  1. Verify forwarding destination number is working

  2. Test by calling forwarding destination directly

  3. Check signal strength on destination device

  4. Disable and re-enable call forwarding

  5. Contact carrier support

Call Forwarding Stops Working Randomly

Possible Causes:

  • Device software update reset settings

  • SIM card issues

  • Carrier network problems

  • Battery optimization killed Phone app

Solutions:

  1. Check call forwarding is still enabled in settings

  2. Re-enable call forwarding

  3. Disable battery optimization for Phone app

  4. Restart device

  5. Remove and reinsert SIM card

  6. Contact carrier to verify forwarding is active on their end

Caller Hears Busy Signal Instead of Forwarding

Possible Causes:

  • Forwarding number is busy or unavailable

  • Forwarding failed to activate properly

  • Carrier limitation on simultaneous calls

Solutions:

  1. Test by calling forwarding number directly

  2. Ensure forwarding number can receive calls

  3. Disable and re-enable call forwarding

  4. Use "Forward when busy" option instead

  5. Contact carrier support

Alternative: Voicemail Instead of Forwarding

If call forwarding isn't available or too expensive, use a voicemail strategy:

Professional Voicemail Script

Text-Only Strategy: Direct callers to text instead of leaving voicemail, improving response time and keeping communication in GHL.

Recommended Message:

"Hi, this is [Your Name] with [Your Business]. This number is used exclusively for texting. If you'd like us to call you back, please send us an SMS, or you can call us directly at our office at [your main phone number]. Thank you!"

Why This Works:

  • Trains contacts to text (which syncs to GHL)

  • Provides alternative number for urgent calls

  • No forwarding fees

  • Professional and clear

Set Up Voicemail

  1. Open Phone app on Android

  2. Go to Settings → Voicemail

  3. Set up voicemail if not already configured

  4. Record custom greeting with the script above

  5. Test by calling yourself

Next Steps

After setting up call forwarding:

  1. Verified Caller ID - Display your WhatSnap number when calling from LeadConnector

  2. Missed Call Text Back - Auto-text missed callers (alternative to forwarding)

  3. Making Calls - Learn about call functionality with WhatSnap

  4. SMS Installation Guide - Set up your Android device
