10 OpenPhone (Quo) Alternatives for Your Business

OpenPhone doesn't exist under that name anymore. On 23 September 2025 it rebranded to Quo, raised $105 million, and kept the same product, apps and phone numbers.

What didn't change is the shape of the bill. Quo still charges per user, from $15 to $35 per user per month on annual billing, and bills international calls and texts by the minute and the message.

It's a good business phone for small teams that mostly take calls and texts. It's a weaker fit if your team makes outbound sales calls all day, because there's no power dialer, or if you need calls to sit in the same workflow as your email and LinkedIn outreach.

This guide compares the ten alternatives worth a real look, with pricing taken from each vendor's pricing page in October 2026 rather than a 2024 screenshot.

TL;DR: the 10 best OpenPhone alternatives#

What is OpenPhone, now Quo?#

OpenPhone, renamed Quo in September 2025, is a cloud VoIP phone system for small and growing teams. Each user gets a local or toll-free number that works from the desktop, web and mobile apps, with calling and texting to the US and Canada included.

According to Axios, the rebrand came with a $105 million raise, $96 million of it from General Catalyst's Customer Value Fund, when the company served around 90,000 customers. Existing accounts, numbers and apps carried over unchanged.

The 2026 product is built around three plans.

• Starter, $15 per user per month billed annually or $19 monthly. One number per user, US and Canada calling and texting, voicemail transcripts, API access and the Sona AI agent with 1,000 free credits (about 10 calls).
• Business, $23 annually or $33 monthly. Adds AI call summaries and transcripts on every call, IVR, HubSpot and Salesforce integrations, automatic call recording, analytics and live chat support.
• Scale, $35 annually or $47 monthly. Adds AI call tags, dedicated onboarding and inbound phone support.

Extra numbers are $5 per month each, automated SMS is $0.01 per segment, and Sona call bundles run from $25 per month for 40 calls to $199 per month for 600 calls.

Why teams look for an OpenPhone alternative#

The reasons are consistent across 2026 reviews on Capterra, where Quo sits at 4.2 from 64 reviews.

Most of them come back to one question. Is your phone a customer line, or a prospecting tool? Quo is built for the first, and the friction shows up when a team tries to use it for the second.

• Per-user pricing on every plan. Every new hire adds $15 to $47 a month, and the AI summaries most teams want sit on Business, not Starter.
• No power dialer. Quo is built for answering and texting. Reps who dial through a list of 80 prospects a day click each number by hand.
• International is metered. Calls and texts outside the US and Canada are billed per minute and per message, for example $0.03 to $0.48 per minute to the UK and $0.07 to $0.09 per minute to India.
• Texting setup friction. US business texting needs A2P 10DLC carrier registration before messages flow, and reviewers report slow number porting and registration.
• AI is sold in bundles. The Sona AI agent covers about 10 calls free, then moves to paid call tiers with per-call overage.
• Support on complex issues. Reviewers praise day-to-day support but report slow resolution on porting, dropped calls and sync failures.
• Calls live apart from outreach. There are no email sequences, LinkedIn steps or WhatsApp steps, so outbound teams run their prospecting in a second tool.
• Short trial. Seven days is tight for testing number porting and carrier registration.

None of that makes Quo a bad phone system. It means the right alternative depends on which of those problems sent you looking.

How we evaluated these OpenPhone alternatives#

Each tool was scored the same way, using each vendor's live pricing page in October 2026.

1. Real cost for a five-person team, with seat minimums and add-ons included.
2. Pricing unit, per user, per license, per account or usage-based.
3. Outbound calling, and whether a power or predictive dialer is included, an add-on or missing.
4. AI features, and whether transcription and summaries are on the base plan or metered.
5. Texting and international reach, including carrier registration and per-minute rates.
6. Channels beyond the phone, specifically email, LinkedIn and WhatsApp.
7. User reviews on G2 and Capterra, read for the recent one and two-star pattern rather than the average alone.

Pricing and ratings checked October 2026. Phone vendors change prices often, so confirm on the live page before you buy.

The 10 best OpenPhone alternatives#

Every review below follows the same playbook. Quick facts, what the tool does well, where it beats Quo, honest pros and cons, real pricing, and a switch-or-stay verdict.

1. SmartReach.io#

SmartReach.io is a cold email software built for outbound teams, and its Sales Engagement plans put calls through a built-in power dialer in the same sequence as email, LinkedIn and WhatsApp. That makes it the OpenPhone alternative for teams whose phone is a prospecting tool rather than a customer line. It's rated 4.6 on G2 from 60 reviews and 4.7 on Capterra from 27 reviews as of October 2026.

The difference from Quo is the workflow around the call.

In Quo, a call is something a rep makes from a contact list. In SmartReach.io, a call is step three of a cadence. A sequence can open with an email, send a LinkedIn connection request, queue a call on PowerCaller, and follow up on WhatsApp, and a reply on any of those channels pauses every other step for that prospect. Nobody dials a lead who answered the email an hour ago.

Take Amy, a senior SDR working 60 accounts a week. On Quo she'd keep a call list in one tab and her email sequence in another, and check both before every dial. In SmartReach.io her call tasks arrive already filtered, so when a VP replies to Tuesday's email, Wednesday's call step for that prospect simply disappears from her queue. How many awkward "I just replied to you" calls does that save in a quarter?

The other difference is the bill. SmartReach.io has no per-seat pricing. Plans scale by active prospects, and every plan above Basic includes unlimited users and unlimited sending email accounts. Calling and LinkedIn seats are bundled into the plan rather than charged per user.

It also works as a sales engagement platform for teams replacing Outreach or Salesloft, and it syncs two-way with HubSpot, Salesforce, Pipedrive and Zoho.

SmartReach.io's calling view, where call steps sit inside the outreach sequence.

What SmartReach.io's calling includes#

• PowerCaller power dialer. Works a day's call list from a single screen, with the next number loading as you hang up.
• Calls inside the cadence. Call steps sit in the same email, LinkedIn and WhatsApp sequence, with a reply-pause rule across every channel.
• Campaign call scripts. The pitch shows on screen during the call with merge tags filled in.
• Listen, whisper and barge-in. Three levels of live coaching for managers.
• Call recording, transcription and sentiment. Every call stored and searchable, tagged positive or negative and tied back to the account.
• Call dispositions and tasks. Tag the outcome and trigger the next step, with reminders, snooze and reschedule for callbacks.
• Reach across 200+ countries. Pick a calling number for the country you're dialing, with personalized caller ID per campaign and local calling on the Scale plan.
• Mobile calling app on every plan, and two-way CRM sync with HubSpot, Salesforce, Pipedrive and Zoho.

Pricing of SmartReach.io#

Email-only teams can start on Email Outreach plans from $29 per month. See every plan on the pricing page.

2. dialnote#

dialnote is an AI-powered VoIP business phone system built around the calls that come in. Where Quo gives a small team a shared number and a tidy message thread, dialnote adds an AI voice agent that answers around the clock, qualifies the caller, books meetings and routes anything high-intent to a human. Plans are one flat monthly price per account, and Team and above include unlimited users.

One thing worth being straight about. dialnote is an inbound system. It runs the line your customers and prospects call, and it isn't a dialer for working a prospect list. If you're leaving Quo over outbound volume, SmartReach.io above is the tool built for that job. Teams often run both, dialnote on the inbound line and SmartReach.io on the outbound sequence.

How to choose the right OpenPhone alternative#

The right tool is the one that fixes your reason for leaving Quo. Work through these questions in order.

1. Decide what your phone is for. If it's mainly inbound calls and texting customers, compare business phones like dialnote, Dialpad, RingCentral and Nextiva. If it's outbound prospecting, you need a dialer, which points to SmartReach.io or Aircall.
2. Count the channels you need together. If calls are one touch in a sequence with email, LinkedIn and WhatsApp, only SmartReach.io keeps them in one workflow with a shared reply-pause rule.
3. Price it for your real team. Multiply the per-user price by headcount, then add seat minimums, AI add-ons, extra numbers and texting fees. Aircall and Dialpad Pro both have three-user minimums.
4. Check international costs. If you call outside the US and Canada, compare per-minute rates, and note Grasshopper's $500 international deposit.
5. Plan for texting compliance. US business texting needs A2P 10DLC registration on every provider. Ask how long it takes and what it costs.
6. Test on real calls during the trial. Port a spare number, make a day of real calls, and check call quality and CRM logging before you move your main line.

The short version#

If inbound calling is your job, dialnote, Dialpad, Aircall, RingCentral and Nextiva are the closest upgrades. If you're a solo operator, Grasshopper costs less. If you build software, Twilio gives you the raw pieces.

For outbound sales teams, SmartReach.io is the pick. It's a cold email software whose Sales Engagement plans run calls through PowerCaller in the same sequence as email, LinkedIn and WhatsApp, from $39 per month, with unlimited users from the Plus plan up. Run a week of real calls in the trial and let the connect rate decide.
