Many small businesses start with a free Google Voice number. As the business grows, some owners want features a personal Google Voice account isn't built for, like a phone menu, a shared line for a team, or a service that answers when nobody can. This guide covers the main kinds of alternatives in neutral terms. Features and prices change, so confirm details with each provider.
Why businesses look past Google Voice
- Personal vs. business accounts. Google offers Google Voice for personal accounts and a separate Google Voice for Google Workspace for businesses. Check Google's help pages for which features each version includes.
- Automated systems. Google says forwarding calls from a personal Google Voice number to an automated system isn't supported, and it points businesses that need an auto attendant to Google Workspace.
- Coverage when you're busy. Google Voice rings your linked phones and devices. If no one picks up, the caller goes to voicemail unless you've set up something else.
The main types of alternatives
1. Google Voice for Google Workspace
If you already use Google Workspace, its paid Google Voice add-on is the closest step up. It's managed by an admin and supports ring groups and auto attendants. See Google Workspace: Google Voice for current plans.
2. Business VoIP and cloud phone systems
Cloud phone services give you a business number that rings on desk phones, computers and mobile apps, usually with phone menus, ring groups, voicemail and call routing. Well-known providers include RingCentral, Nextiva, Dialpad, Ooma Office, Zoom Phone and Grasshopper. Plans and features differ, so compare them on each provider's site.
3. Your carrier's business line
Cable and phone companies such as Verizon, AT&T, Comcast Business, Optimum and Spectrum Business sell business phone lines, often bundled with internet. These usually include call forwarding and voicemail features. See our carrier forwarding guide for examples.
4. Live answering services and virtual receptionists
A live answering service has people answer calls for your business, take messages and sometimes book appointments. You usually keep your number and forward calls to the service. Pricing models vary by provider.
5. AI receptionists
An AI receptionist answers forwarded calls with an AI voice agent. It can answer common questions, take messages, collect lead details and, depending on the setup, book appointments. It's usually added on top of your existing number rather than replacing your phone system. It has limits: it follows the information and rules you give it, and it should hand off or take a message when a call needs a person. A good one tells callers it's an AI. Our guide What is an AI receptionist? covers what it can and can't do.
RaheemAI is one option in this category. Ava, our AI receptionist, answers calls you forward to her, tells callers she's an AI, and emails you the details.

Questions to ask before you switch
- Can I keep my current number, and how long does porting take?
- What happens when nobody answers: voicemail, a menu, forwarding, or an answering service?
- How is it billed: per user, per minute, per call, or a flat monthly fee? Are there setup fees or contracts?
- Does it work on the phones my team already uses?
- How are calls recorded and stored, and how are callers told?
- If I want business texting, what carrier registration is required? Many providers require it before business texts can be sent.
- How do I cancel, and can I take my number with me?
Keeping your number
You don't always have to switch systems to fix missed calls. Forwarding keeps your number where it is and adds coverage on top. If you do switch providers, the FCC says you can generally keep your number when you stay in the same area. Google Voice also has its own steps for porting a number out. Don't cancel your old service before the port is complete.
