Quo Phone System: How It Works for a Small Business (2026)
Quo is the business phone app that was called OpenPhone until September 2025. No desk phones, no PBX box in the closet: a business number that lives in apps on your laptop and cell.
If you’ve seen the ads and want to know what you’d actually be running day to day, this is the walkthrough.
The quick answer: Quo gives each user a US or Canadian business number (new or ported), apps for web, desktop, iPhone and Android, one shared inbox per number for calls and texts, and a visual call flow builder with business hours, phone menus, ring groups, voicemail and an AI agent called Sona. It works well for small teams that text customers a lot. Growing teams hit its edges: no call queues or true round-robin, no way to assign a conversation, no deals pipeline, no email, and an AI that texts a booking link instead of booking. If your phone is really a lead desk, book a call with the Carly team to see Carly Phone answer, call back and book leads onto your team’s calendars.
What you’re buying with Quo
Quo is a VoIP phone system sold per seat. Every seat includes one number, and calls and texts to US and Canadian numbers are included under Quo’s fair use policy. It’s software only, so there’s no desk phone option. Calls, texts, voicemails and recordings sit in one thread per contact, like a messaging app, and a number can be shared by several teammates with one history everyone sees.
Whether it’s any good is covered in our Quo review. This page is about how it works.
Numbers: local, toll-free or the one you already have
- Local numbers in every US state except Alaska, and across Canada.
- Toll-free numbers (800 through 888), all text-enabled, though Quo’s help center says they can’t send group texts.
- Extra numbers for a second location or brand at $5 a month each, each with its own inbox and settings.
To keep your current number, you port it in from the app. Quo charges nothing, and its help center says most ports finish in 3 to 7 business days and typically can’t be expedited. A ported cell number becomes VoIP, so its SIM and cell service are switched off.
Quo only offers US, Canadian and North American toll-free numbers. There are no international numbers and no fax.
The apps: web, desktop, iPhone and Android
Calls ring every device you’re signed into, and you choose which business number shows as caller ID when you dial out, so your personal cell stays private. Reviewers praise how clean the apps feel, and they also report dropped calls and lag on weak Wi-Fi or cell data. Test it on the connection your team actually works from.
Inboxes and shared numbers
Each phone number gets its own inbox, with Chats, Calls and Tasks tabs. On Starter, up to 10 users can call and text from one shared number. On Business, Quo’s help center says up to 100. Up to 10 people ring at once, and bigger teams need ring groups.
Teammates coordinate with:
- Conversation status: Open, Unread or Done, shared by the whole team.
- Internal threads: private comments with @mentions on any message, call or voicemail.
- Tasks: to-dos with an assignee and due date, created from a conversation. Starter caps you at 10 open tasks.
Call flows: how Quo routes a call
Each number has a call flow, built on a drag-and-drop canvas and published when it’s ready.
| Step | What it does | Plan |
|---|---|---|
| Business hours | Splits calls into during-hours and after-hours paths | All plans |
| Ring users | Rings everyone at once or in random batches | All plans |
| Custom ring groups | Rings teammates in the order you set | Business and Scale |
| Phone menu | ”Press 1 for sales,” keys 0 to 9, a couple of levels deep | Business and Scale |
| Play audio | Plays a greeting or announcement | All plans |
| Voicemail | Custom greeting, automatic transcription | All plans |
| Forward | Sends the call to a US or Canadian number | Varies by plan |
| Sona | Hands the call to Quo’s AI agent | All plans |
| Go to and Branch | Reuses a step, or routes by who’s calling (Branch is in beta) | Branch is Business and Scale |
Recording is manual on every plan. Automatic recording and AI summaries on every call start on Business, and on Starter summaries only cover calls Sona handled.
Sona sits inside the flow: after nobody answers, after hours, or behind a menu option. It answers questions from a knowledge base you give it, takes messages, texts the caller a link and transfers to a teammate. About 10 Sona calls a month are included, then credit tiers kick in. Our Quo AI guide goes deep on Sona.
Texting and the 10DLC registration step
Texting is why most teams pick Quo, and it has a setup step people don’t expect. US carriers require businesses texting from local numbers to register with The Campaign Registry (A2P 10DLC).
- No US texting until you’re approved. Quo’s help center says unregistered numbers can’t text US numbers at all.
- No registration during the 7-day trial. It needs a paid plan, so the trial has no US texting.
- Approval time varies. Quo says most approvals take 24 to 48 hours, some stay pending for up to 20 days, and rare cases run past 30.
- Fees pass through: $19.50 once, plus $1.50 to $3 a month.
Plan your go-live around this, especially if you’re porting a number customers already text. Once approved, you get MMS, group texts of up to 10 people, scheduled texts, saved replies and auto-replies. There’s no mass texting in the app, and texts sent through the API, Zapier or Make cost 1 cent per segment.
Quo plans at a glance (as of September 2026)
| Plan | Billed monthly | Billed annually | What it adds |
|---|---|---|---|
| Starter | $19/user/mo | $15/user/mo | A number per user, US and Canada calling and texting, voicemail transcripts, Sona with about 10 calls a month |
| Business | $33/user/mo | $23/user/mo | AI summaries on every call, phone menus, custom ring orders, transfers, HubSpot and Salesforce, analytics, auto recording |
| Scale | $47/user/mo | $35/user/mo | AI call tags, dedicated onboarding, priority support, inbound phone support |
Most growing teams land on Business, because phone menus, ring order and CRM sync start there. For team math with extra numbers, registration fees and Sona credits, see our Quo pricing breakdown.
What a growing team hits in Quo
These are the limits teams run into once calls become a sales or intake operation, all from Quo’s own help center and product pages.
No call queues. When everyone’s busy, the call moves to the next step: voicemail, forwarding or Sona. Quo’s ACD page argues that “call queues aren’t necessary” and “often deliver a poor experience to callers.”
No true round-robin. For round-robin, Quo’s help center suggests building custom ring groups and rotating members by hand every week.
No conversation assignment. Quo’s help center describes no way to make a conversation belong to one person. The only assignee field is on Tasks, and there’s no cross-inbox task view: Quo says you switch inboxes to see everything assigned to you.
No deals or pipeline. To track a sale, Quo’s help center suggests a multi-select “Lead status” contact property running from Prospect to Closed Won.
One inbox per number. A business with a sales line, a service line and a second location works three inboxes.
No email. Quo is calls and texts. Customer email stays in Gmail or Outlook, separate from the phone thread.
US and Canada only. No international numbers, and forwarding only reaches US and Canadian numbers.
Sona answers but doesn’t book. Quo says Sona “can’t make outbound calls right now,” and booking means texting the caller a booking link. It can’t reschedule or cancel on a live call.
Call flow fine print:
- Forwarding is the end of the line. Forwards can’t be chained, and if the outside number doesn’t pick up, the call doesn’t come back to your Quo voicemail.
- Call flows can’t be copied between numbers, so each one is built by hand.
- Business hours allow one continuous window per day. Split shifts like 9 to 12 and 2 to 5 aren’t supported.
None of this matters for a three-person shop that answers its own phone. It matters a lot when missed calls are missed revenue.
Who the Quo phone system fits
Quo fits well for:
- Solo operators and teams of 2 to 10 who want a business number off personal cells
- Texting-heavy businesses: home services, real estate, property management, agencies
- Home services teams on Jobber. On Business and Scale, Quo syncs call summaries and contacts with Jobber, and Sona can create a Jobber request during a call.
- Owners happy to build their own call flows and knowledge base
Teams tend to outgrow it when:
- New leads need a callback in minutes, including the ones from a web form
- The AI has to book the appointment, not text a link and hope
- Someone needs to own each conversation, and a manager needs to see who’s on what
- Deals, email and the phone need to live in one place

When your phone is really a lead desk: Carly Phone
Carly is an AI assistant for businesses, and Carly Phone gives it a business phone line. It’s built for teams where the phone is how new business arrives.
Say Michael runs a roofing company in Denver. A homeowner fills in the quote form on his site at 6:40pm. Within minutes Carly calls them, asks Michael’s qualifying questions (address, roof age, insurance claim or not), checks his two estimators’ real calendars and books a quote call with whoever is free first. The homeowner gets the invite with the call link. If nobody picks up, Carly leaves a voicemail, follows up by email and text, and tries again a few minutes later. The call and the answers land in HubSpot before Michael is home. See Carly Phone on a call.
What Carly Phone does:
- Answers inbound calls and calls new leads back. Outbound calls fire when a lead arrives from a Carly form, a webhook, or a new record in Salesforce, HubSpot, Dynamics 365, Pipedrive or Carly’s CRM, only inside your calling hours (8am to 8pm by default), with a cap on attempts per lead per day.
- Qualifies with scripts you type out, up to 25 questions scored the same way every time, and routes each lead to the right person or team by your rules.
- Books into your team’s real calendars while the caller is on the line, with round-robin across the team and the Meet, Teams or Zoom invite sent for you.
- Routes calls to your people: transfers, ring groups at once or in order with a press-1 screen so a teammate’s personal voicemail doesn’t swallow the call, phone menus, business hours, and voicemail with transcription.
- Texts both ways with an AI SMS agent that can also book, and STOP and HELP handled automatically.
- Gives every conversation an owner: a shared inbox of calls and texts, assignment by hand or on the first reply, and a per-thread “Carly replies / human replies” switch.
- Logs every call to HubSpot, Salesforce or Dynamics, with the caller’s answers saved as contact fields, plus analytics for answer rate, qualified and booked.
- Brings the rest of Carly: email, calendar, a CRM with a deals pipeline, and free Zapier-style workflows with ready-made templates. Carly connects to thousands of apps.
The Carly team sets the line up with you, so nobody on your side is building call flows at night. Book a call with the Carly team and bring your current call flow.

FAQ
How does the Quo phone system work?
Quo gives each user a US or Canadian business number that works in apps on the web, desktop, iPhone and Android. Calls and texts for each number land in a shared inbox, and a visual call flow decides how calls ring, what happens after hours, and when voicemail or the Sona AI agent picks up.
Is Quo the same as OpenPhone?
Yes. OpenPhone renamed itself Quo in September 2025. It’s the same company and the same apps, and Quo’s help center still says “Quo, formerly OpenPhone.”
Does Quo work with desk phones?
No. Quo is app-only. If your front desk needs a physical handset, see our best small business phone systems roundup.
Can I keep my existing number with Quo?
Yes. Porting a US, Canadian or toll-free number in is free, and Quo’s help center says most ports complete in 3 to 7 business days. A ported cell number loses its cell service once it moves.
Can I text customers during the Quo free trial?
Not US numbers. Texting US numbers requires carrier registration, and only paid accounts can register, so the 7-day trial has calling but no US texting.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
