Overview

Forward calls from your existing phone number to your 800.com number so you can keep the number your customers already know while using features like AI Agents, IVR, Enhanced Caller ID (ECID), call recording, transcriptions, and 800 Intelligence.

Select your phone provider below for setup instructions and forwarding codes.

Tip: If you're forwarding missed calls from an iPhone, be sure to turn Live Voicemail off. Otherwise, your iPhone may answer the call before it can be forwarded to your 800.com number.

What You'll Find in Each Guide

Each provider guide includes:

• Forward All Calls — Route every incoming call to your 800.com number.
• Forward Missed Calls — Send unanswered calls to 800.com (when supported).
• Forward Busy Calls — Forward calls only when you're already on another call (when supported).
• Disable Forwarding — Turn call forwarding off when you no longer need it.
• Provider Notes — Helpful information about carrier limitations, iPhone compatibility, and additional setup recommendations.

Before You Begin

Before configuring call forwarding, make sure you have:

• An active 800.com account
• An active 800.com phone number
• Access to your phone provider's call forwarding settings
• Your 800.com phone number available as the forwarding destination

Important for iPhone users: If you're using missed-call or conditional call forwarding, turn off Live Voicemail. Otherwise, your iPhone may answer the call before it can be forwarded to your 800.com number.
