Google Voice call forwarding: read this first

We tested Google Voice forwarding against a live AI receptionist across repeated real calls, and the honest answer is: do not build on it. Google Voice was designed to ring humans, and it actively resists handing calls to an automated system. Here is exactly what breaks, and the two setups that work instead.

tested verdict

There is no dial code on this page because forwarding Google Voice to an automated receptionist fails roughly half the time, by Google's design.

We ran repeated live calls through a linked AI line before writing this. The two setups that actually work are below, and both take the frustration out permanently.

The two paths that work

1Option 1, live today: get a new AI number and start giving it out as your business line. Nothing about your Google Voice setup changes, and the AI answers every call to the new number from minute one.
2Option 2, keep your number: port it from Google Voice to your AI provider. Google charges a one-time $3 unlock fee, the transfer takes roughly two weeks, and your number keeps working the whole time. After cutover, the AI answers your existing number directly with nothing in the middle.

The quirks nobody tells you

We run these setups on live business lines. These are the failure modes we actually hit.

The "press 1" gate is the killer

When a linked number answers quickly, Google Voice plays a challenge to the answerer: "you need to press one to take this call." A human presses 1. An AI answers and starts talking instead, the keypress never comes, and your caller sits in ringback until Google gives up and sends them to Google Voice voicemail. In our live tests, roughly half of all calls died at this gate.

Verification codes go nowhere

Adding a forwarding number to Google Voice requires a verification code sent to that number. The default is a text message, and AI phone lines are voice-only, so the code lands in a mailbox no one can read. The verify-by-phone option can work, but it is the first of several fragile steps, not the last.

Porting out is fully supported

Google documents the exit: unlock the number in Google Voice settings for $3, then port it to the new carrier. Text messages to the number and Google Voice voicemail stop working after the port, so check whether you text customers from it first.

the other half of the setup

A forwarding code needs something worth forwarding to

Corex's AI receptionist answers the Google Voice calls you miss, around the clock. It answers questions about your business, books the job, takes the message, and puts urgent callers through to you. Live in minutes with a local number, from $149 a month.

Common questions

Can I forward my Google Voice number to an answering service at all?

Technically sometimes, reliably no. Google Voice requires linked numbers to accept calls with a keypress that automated systems do not perform, so a meaningful share of calls never connect. We tested this live and stopped recommending it.

How do I move my Google Voice number to an AI receptionist?

Port it out. Unlock the number in Google Voice settings ($3 one-time), then file the port with the new provider. It takes about two weeks, the number works throughout, and afterward the AI answers it directly.

What do I lose when I port out of Google Voice?

Google Voice voicemail, the Google Voice app, and texting on that number. Calls simply move to the new provider. If you text customers from the number, plan for that before porting.
