Google Voice has no dial codes - forwarding lives at voice.google.com and takes about 3 minutes: link the destination number, verify it with a 6-digit code, and switch it on under Settings, then Calls. This guide covers every click, including how to grab the verification code when an AI answers the call.
Personal and most Workspace Voice accounts work. One caveat from Google's own docs: linked numbers are not available on SIP Link accounts.
Your AskSiya dashboard shows the dedicated local US number Siya answers. The 7-day free trial creates one in minutes, no credit card needed.
Google verifies new linked numbers with a code delivered by call or text. Siya answers the verification call, and the code shows up in her live transcript.
Unlike the big carriers, Google Voice exposes no busy or no-answer dial codes - it rings all of your enabled devices and linked numbers at once, and unanswered calls fall to Google's voicemail. Because Siya answers in about one ring, leaving her linked alongside your own devices means she will effectively win every call. Three practical patterns:
If you need true busy/no-answer forwarding, do it one layer down: port or forward the underlying business line at the carrier level instead (see our Verizon, AT&T and T-Mobile guides).
Test it by calling your Google Voice number from another phone: Siya should answer in about one ring, greet callers with your business name, and the conversation lands on your dashboard with a transcript. Try ordering something or asking for hours to see the full flow.
To turn it off: go to Settings, then Calls, and toggle the Siya linked number off under Call forwarding (or remove it entirely under Linked numbers). Re-enable the devices you switched off and calls ring exactly as before. Nothing about your Google Voice number changes.
Google Voice forwards the call; Siya answers it. She picks up 24/7 in about one ring, takes restaurant orders and hotel bookings straight onto your dashboard, speaks 100+ languages, and starts at $19/mo for 60 minutes with a 7-day free trial, no card required. Plans auto-upgrade as your call volume grows, so callers never hit a busy signal. See what Google voicemail is quietly costing with the free missed call revenue calculator.
On a carrier line instead? See the guides for Rogers, Bell, TELUS, Freedom Mobile, AT&T, Verizon and T-Mobile.
Choose verification by call. Google's automated voice reads a 6-digit code to whoever answers - Siya picks up, and the code appears in the live transcript on your AskSiya dashboard. Read it there and type it into Google Voice. Text verification also works if the destination number accepts SMS.
Not with dial codes - Google Voice rings enabled devices and linked numbers together, and unanswered calls fall to Google voicemail. Since Siya answers in about one ring, the practical patterns are: let her take everything and transfer real-person requests to your cell, toggle her on after hours only, or use Custom call forwarding for specific contacts.
Yes. Forwarding through a linked number changes nothing about ownership - callers still dial your Google Voice number, and you can remove the link any time under Settings, then Linked numbers.
Two common reasons: SIP Link accounts do not support linked numbers, and some Google Workspace Voice policies hide the setting. Check with your Workspace admin, or manage the number from a personal Google Voice account instead.
