Carrier Call Forwarding Guide (Verizon, AT&T, T-Mobile & VoIP)

Exact step-by-step dial codes and instructions to set up conditional and unconditional call forwarding to your Heyly AI number.

This guide provides the exact dial codes and configuration steps for all major mobile and business VoIP carriers so your calls route automatically to your Heyly AI receptionist.

Unconditional vs. Conditional Call Forwarding

Before dialing, determine which forwarding mode best fits your operational workflow:

  • Unconditional Forwarding (All Calls): Every incoming call routes straight to Heyly immediately. Your cell phone or desk phone will not ring. Best if Heyly is your full-time front line.
  • Conditional Forwarding (Rollover / Overflow): Your phone rings normally for 3 to 4 rings. If you are busy, driving, on a job, or outside business hours, the call automatically rolls over to Heyly instead of your carrier's voicemail.

1. Verizon Wireless & Verizon Business

Conditional Call Forwarding (Rollover when busy or unanswered) - **To Enable**: Dial `*71` followed by your 10-digit Heyly number (e.g. `*715551234567`) and press **Call / Send**. - You will hear a confirmation tone or brief announcement. - **To Disable**: Dial `*73` and press **Call / Send**.

Unconditional Call Forwarding (All calls immediately) - **To Enable**: Dial `*72` followed by your 10-digit Heyly number (e.g. `*725551234567`) and press **Call / Send**. - **To Disable**: Dial `*73` and press **Call / Send**.

Customizing Ring Duration (Before Heyly Answers) You can specify how many seconds your phone rings before transferring to Heyly (in increments of 5 seconds, between 5 and 30 seconds): - Dial `**61*<HeylyNumber>**[Seconds]#` - *Example (Forward after 15 seconds / ~3 rings)*: `**61*5551234567**15#`

  3. - Add your Heyly phone number to the forwarding list.
  4. - Set the ring order to Simultaneously or In Order (ring your softphone first for 15s, then forward to Heyly).
  5. - Set After-Hours rules to forward directly to your Heyly number.
  1. Grasshopper:
  2. - Go to Settings → Extensions → Call Forwarding Settings.
  3. - Add your Heyly number and set forwarding schedule to *24/7* or *After Hours*.
  1. Dialpad / Vonage:
  2. - Navigate to your main department number settings.
  3. - Set the fallback / timeout routing destination to your external Heyly phone number.

How to Test Your Setup

Once you have activated call forwarding: 1. Use a different phone (such as a colleague's mobile or personal line) to dial your main business number. 2. If you set up unconditional forwarding, Heyly should pick up within 1 to 2 rings. 3. If you set up conditional forwarding, let your phone ring without answering. After 3 to 4 rings, the call should roll over to Heyly. 4. Have a brief conversation with Heyly (e.g. ask for hours, pricing, or try booking a test appointment) and verify that the call transcript and Google Calendar / Jobber booking appear on your Heyly Dashboard.
