OpenPhone Alternatives

Dialpad is an AI-first business phone system. Dialpad Connect, its phone line, puts calls, video meetings and messaging in one app, and it transcribes calls in real time and writes a summary when you hang up. That is the main reason it ranks first for Quo users: the AI that Quo keeps for its Business plan, at $23, comes with Dialpad's entry plan.

Connect Standard costs $15 per user a month on annual billing, exactly Quo Starter's annual price, and includes real-time transcripts and instant call summaries. Read the billing line, though. On monthly billing Standard is $27, $8 more than Quo Starter's $19, so a team that refuses annual contracts pays more on Dialpad. Pro, at $25 annual or $35 monthly, adds CRM integrations, 24/7 support and multi-office management, and the Enterprise plan, priced on request, adds SSO and a 99.9% uptime figure. Dialpad also supports local numbers in over 50 countries, and its apps connect to other tools through Dialpad's Zapier integration.

The contract is where Dialpad bites. Annual terms renew for the same length unless you give 30 days' notice, and leaving early leaves you liable for the remaining charges. If you are already weighing the reverse move, our Dialpad alternatives guide lists what people miss once they leave it.

RingCentral is the heavyweight of business phone systems. RingEX, its phone plan, bundles calling, business SMS, video meetings and team messaging, and RingCX adds a full contact center when your support team outgrows a shared number. For a Quo user, it is the move you make when the company grows past one office and routing becomes a project of its own.

Core costs $20 per user a month on annual billing, or $30 on monthly billing, for accounts of up to 100 users; above that, RingCentral quotes on request. Against Quo, that is $5 more per seat than Starter on the same annual basis, but Core already includes unlimited domestic calling, on-demand call recording and 100 toll-free minutes. Advanced, at $25 annual or $35 monthly, adds CRM integrations, multiple sites and core reporting. Extra local or toll-free numbers cost $4.99 a month, a cent less than Quo's $5. For custom workflows, you can wire RingCentral into Make.

Texting, the thing Quo users do most, is where it falls short. Core includes 25 SMS per user a month, Advanced 100 and Ultra 200, while Quo includes unlimited US and Canada texting, subject to fair use. A team that texts customers all day pays for the $25 Business SMS Booster or moves up a plan. Our guide to switching from RingCentral covers what its own users complain about.

Nextiva is a unified communications platform that has moved toward customer service: calls, business texting, video and customer conversations sit in one workspace, with a basic CRM and ticketing system on the entry plan. For a Quo team that starts handling support requests by phone and text, that ticketing layer is the difference.

NEXT Core costs $15 per user a month on annual billing, the same as Quo Starter, or $23 on monthly billing, $4 above Quo's $19. The annual price has a condition: it applies to new customers with 1 to 100 employees signing a 12-month or longer term. NEXT Engage, the plan Nextiva marks as most popular, is $25 annual against $50 monthly, so skipping the contract doubles the bill. Core includes 100 business text messages per user, and other apps connect through Nextiva's Zapier integration. Nextiva also runs a limited-time switching offer, up to 12 months free, whose conditions are worth reading before you count on it; our Nextiva alternatives guide covers the tools it is most often weighed against.

The catch is that AI is rationed. Core includes 50 AI transcriptions and 50 AI summarizations, Engage 200, and only Scale, at $75, makes them unlimited. XBert, the AI agent, costs $1.50 per conversation on top. Quo Business includes AI call summaries and transcripts at $23 with no such count, so Nextiva only wins on AI for light use.

Zoom Phone is the cloud phone system inside Zoom Workplace. If your company already lives in Zoom meetings, adding phone keeps one app and one management portal. Every US & CA plan includes domestic SMS and MMS, call recording, online fax (50 pages a month, unlimited on Business Plus), AI post-call summaries and integrations with Salesforce, Slack, Microsoft and Google.

Its Metered seat is the second cheapest on this page, after Google Voice Starter at $10. US & CA Metered costs $10.50 per user a month, $4.50 less than Quo Starter's annual price, for people who make a few calls; domestic minutes are then billed on top. US & CA Unlimited costs $16, a dollar more than Quo Starter. Monthly billing exists at $18 for Unlimited and $12 for Metered. The US & CA plans are sold for 1 to 99 licenses, Business Plus for up to 250.

Watch the add-ons, and the texting habits Quo users bring with them. International calling is a $10 monthly add-on, extra numbers cost $5 a month each, like Quo's, and the Customer Engagement Pack is $25 a month. Zoom Phone is built around calls and meetings; a team whose day runs on shared text threads with internal notes, the habit most Quo teams have, should check that workflow in the trial first.

Grasshopper is a virtual phone system for small businesses: you get a business number, extensions and a mobile and desktop app, so calls and texts to the business stay apart from your personal line. It is simpler than Quo, and it prices differently. Quo charges per user; Grasshopper charges per account.

True Solo costs $14 a month billed annually ($168 a year) for one user, one number and one extension. Solo Plus, at $25 a month billed annually ($300 a year), includes unlimited users, one number and three extensions, and Small Business, at $55 ($660 a year), unlimited users, four numbers and unlimited extensions. That flat price is the whole argument: five people sharing one number cost $25 a month on Solo Plus, against $75 on Quo Starter's annual price. Calling minutes are unlimited on every plan, and business texting is unlimited once you complete carrier registration.

The limits are the extras. Each additional number costs $9 a month, against $5 at Quo, and extra extensions $3 on Solo Plus.

Google Voice is Google's business phone service. It gives each user a number that rings on the web, the mobile app and a desk phone, transcribes voicemail and handles US texting, all managed from the Google Workspace admin console. For a Quo team that already runs on Gmail and Google Calendar, it removes a separate vendor.

Starter costs $10 per user a month for up to 10 users, $5 below Quo Starter's annual price, and includes unlimited domestic calling, unlimited US texting, voicemail transcription and call recording, subject to Google's fair-use terms. A one-user Starter is also sold on its own, in the US. Standard, at $20, removes the 10-user cap and adds auto attendants, ring groups and call queuing for ring groups; Premier, at $30, adds automatic call recording and reporting in BigQuery. The multi-user plans are added to a Google Workspace subscription, so count that seat too.

What it lacks is everything around the call. Good value for a Google shop that wants numbers; thin for a team that works its customers through the phone app all day.

Aircall is a cloud phone system built for sales and support teams. Its strength is integrations: more than 250 tools connect, and calls sync to your CRM or help desk. Routing lives in a visual call-flow editor, and Essentials already includes a shared inbox, call recordings with AI transcripts and an IVR. Our full Aircall review scores it 3.2 out of 5, mostly because of price and support.

Essentials costs $30 per license a month on annual billing, $40 monthly, and Professional $50 annual or $70 monthly. Every plan needs at least 3 licenses, so the smallest bill is $90 a month on annual billing even if one person makes calls. Against Quo Business, the plan where Quo adds its HubSpot and Salesforce integrations, that is $7 more per seat on annual billing ($30 against $23). Each plan includes one local or toll-free number, not one per license as at Quo, and extra numbers cost $6 a month. Our Aircall pricing breakdown details the add-ons.

The bill grows through the minimum and the extras. The Salesforce integration starts on Professional, AI Assist Pro costs $49 per seat a month, and HIPAA compliance sits on Enterprise, which needs 25 users. If you are choosing for a sales team, our Aircall alternatives guide covers the tools it is most often compared with.
