OpenPhone, now called Quo, is a business phone for small teams with shared numbers, texting and the Sona AI agent, from $15 a user a month billed yearly. Grasshopper and RingCentral 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.
OpenPhone, now called Quo, is a business phone for small teams: shared numbers, calling and texting in one app, with an AI agent called Sona that answers when nobody can. Teams looking for an alternative usually want one of two things: a different business phone, or an AI that holds the sales conversation itself and books the next step.
Here is what Quo offers, the main alternatives, and where SalesCloser fits. Competitor details come from each vendor’s own website, checked in November 2026.
What Quo (formerly OpenPhone) offers
Quo gives each user a local or 800 business number with calling and texting to the US and Canada, shared numbers your team answers together, voicemail transcripts, phone menus, call transfers and CRM integrations such as HubSpot, Salesforce, Pipedrive and HighLevel. Every plan includes Sona, an AI agent that answers calls 24/7, with 1,000 credits a month (about 10 calls); more Sona calls are sold in credit tiers from $25 a month.
Billed yearly, Quo lists Starter at $15 a user a month, Business at $23 and Scale at $35 ($19, $33 and $47 billed monthly).

Where SalesCloser is different
A business phone makes sure every call reaches your team. SalesCloser is your AI sales team: an AI agent has the sales conversation itself, qualifies the caller and books the next step with the right person.
- 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 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 works next to your phone system. Keep Quo, Grasshopper or RingCentral for your team’s calls and texts, and send sales calls to the agent when you are busy, after hours or during spikes.
What that looks like: a managed IT provider gets calls from office managers asking what it would cost to take over their company’s IT. The phone agent asks how many employees and devices they have, which systems they run and what is going wrong today, explains how an assessment works, and books one with a solutions consultant. Calls from existing clients still ring the team’s shared number.
How to choose
- Keep or pick Quo if your team shares numbers and wants calling, texting, a phone menu, CRM sync and an AI agent for the calls nobody can take.
- Pick Grasshopper if you mainly need a simple business number with unlimited minutes at a low monthly price.
- Pick RingCentral if you want phone, messaging and video meetings for a growing team in one system.
- Pick SalesCloser if your calls are sales conversations and you want an AI agent to qualify callers, answer their questions and book or transfer the ready ones.
What to check before you choose
- Ask how many AI-handled calls the plan includes, and what each extra one costs.
- Ask whether the AI only answers and takes a message, or qualifies and books.
- Calling, consent and recording rules stay your responsibility with any vendor.
