Google Voice is Google’s cloud phone service, from $10 a user a month for teams plus a Google Workspace plan. Quo (formerly OpenPhone) and Grasshopper are alternatives if you want a business phone. SalesCloser does a different job: your AI sales team answers sales calls, qualifies the caller and books or transfers the ready buyers to your team, next to the phone system you already have.

Google Voice is Google’s cloud phone service: a business number that works on your phone, laptop and desk phone, and inside Gmail. Teams looking for an alternative usually want one of two things: a business phone with more team features, or an AI that answers sales calls itself and books the next step.
Here is what Google Voice offers, the main alternatives, and where SalesCloser fits. Competitor details come from each vendor’s own website, checked in November 2026.
What Google Voice offers
Google Voice gives you one number for all your devices, with unlimited domestic calling and texting in available markets, spam blocking and voicemail transcription. Team plans add call transfers and recording, desk phone support, auto attendants and ring groups, call queues, Gemini notes on calls and, on Premier, automatic call recording and transcription with BigQuery reporting.
For teams, Google Voice lists Starter at $10 a user a month (up to 10 users), Standard at $20 and Premier at $30. Team plans require a Google Workspace plan, billed separately.
Google Voice alternatives at a glance

Where SalesCloser is different
A phone service routes the call to the right person. SalesCloser is your AI sales team: when nobody can pick up, an AI agent has the sales conversation itself, qualifies the caller and books the next step.
- It holds the sales call. A SalesCloser phone agent answers calls to your sales line 24/7, asks your qualifying questions, answers from your own knowledge base and books the meeting or transfers a ready buyer to your team.
- It works next to Google Voice. Keep your numbers, ring groups and Gmail voicemail for everyday calls, and send sales calls to the agent when your team is busy, after hours or during spikes.
- It talks to website visitors too. A website agent talks to visitors by chat, voice or video, and a demo agent can show your product by screen share or video.
- It can call back the list. In an outbound campaign, a phone agent calls past inquiries inside your calling hours and books the ones who are ready.
What that looks like: a property management company gets calls from building owners asking what it would cost to manage their units. The phone agent asks how many units they have, where the building is and what they use today, explains how the management fee is set, and books a call with a business development manager. Calls from current tenants still go to the ring group the office already uses.

How to choose
- Keep or pick Google Voice if your team lives in Google Workspace and wants numbers, routing and voicemail inside Gmail and Calendar.
- Pick Quo if your team shares numbers, texts customers a lot and wants CRM sync plus an AI agent for missed calls.
- Pick Grasshopper if you mainly need a simple business number with unlimited minutes at a low monthly price.
- Pick SalesCloser if your calls are sales conversations and you want an AI agent to qualify callers and book or transfer the ready ones. It sits next to your phone system, not in place of it.
What to check before you choose
- Ask what happens to a sales call nobody answers: voicemail, a ring group, or a booked meeting.
- Ask what you pay per user, per number and for any AI features.
- Calling, consent and recording rules stay your responsibility with any vendor.
