7 Best Quo (Formerly OpenPhone) Alternatives Worth Switching To
A phone system that goes down monthly, support you can only reach by email, and a porting process where one user says Quo filed "123456" as the AT&T account number - taking four attempts to fix. That's from r/PhoneSystem. If you're looking for Quo (formerly OpenPhone) alternatives, you've probably hit something similar.
You don't need 15 options. You need to answer one question: do you want a simple business number, a team phone system, or a full UCaaS platform? We've tested all seven of these, and the right pick depends entirely on that answer.
Our Picks (TL;DR)
- Best for growing teams: Nextiva - $15/user/mo, 24/7 customer support
- Best for AI-powered calling: Dialpad - $15/user/mo, real-time transcription baked in
- Best for solopreneurs: Grasshopper - $14/mo flat, no per-user math
What Happened to OpenPhone?
OpenPhone is now Quo. The company rebranded after raising $105M, positioning the move as an expansion into an AI-powered "front office" platform. The centerpiece is Sona, an AI agent that handles calls, qualifies leads, and routes conversations. The core product - shared numbers, texting, call routing - hasn't changed.
Quo holds a 4.7/5 on G2 across 3,294 reviews and serves 90,000+ businesses. The UI is clean and onboarding is fast. The problems show up at the edges.
Why People Switch From Quo
Here's the thing: the complaints are remarkably consistent across Reddit threads.
Monthly outages. Users report being out half the day with calls and messages failing - on a recurring basis. For a phone company, that's inexcusable.
Email-only support. When your phone system is down, waiting for an email reply is maddening. Multiple threads on r/openphone mention this as the final straw.
Porting nightmares. Multiple attempts, weeks of delays, incorrect account numbers submitted to carriers. One user described a four-attempt saga that dragged on for over a month.
SMS compliance friction. Users report waiting over a month for SMS enablement while losing business. If texting is part of your sales workflow, that delay kills deals.
No SSO, MFA, or end-to-end encryption. If your team handles sensitive data, these gaps are a real problem that most reviews gloss over. And there's post-rebrand pricing anxiety - the $105M raise has to fund something. Switching VoIP providers is straightforward enough that the uncertainty alone pushes people to look.
A better phone system means nothing if you're dialing the wrong numbers. Prospeo gives you 125M+ verified mobile numbers with a 30% pickup rate - 3x higher than ZoomInfo. Stop burning call time on dead lines.
Fix the number before you fix the phone system.

The 7 Best Quo Alternatives for 2026
Nextiva
Use this if you're a team of 5-50 that wants to stop thinking about uptime and support. Nextiva's Core plan starts at $15/user/mo annually, matching Quo's Starter annual price and adding 24/7 customer support.
In our experience, Nextiva's support actually picks up the phone - which sounds like a low bar until you've spent a morning refreshing your inbox during an outage. The reliability difference alone justified the switch for two teams we spoke with, both under 20 seats.
Skip this if you need advanced features on the entry plan. Nextiva's Core tier pushes you toward Engage at $25/user/mo or Power Suite CX at $75/user/mo for the full feature set. But for reliability and support, it's the safest bet on this list.
Dialpad
If you liked Quo's Sona AI concept but want something more mature, Dialpad is further along. Real-time transcription, AI call summaries, and coaching suggestions come standard - not as a bolt-on credit system. Pricing starts at $15/user/mo annually, $27/user/mo monthly.
The tradeoff: live coaching, custom playbooks, and CRM integrations are locked behind the Pro tier at $37/user/mo. The base plan gives you solid VoIP with transcription, which is more than most competitors offer at that price.
For sales teams running outbound, the AI coaching alone justifies the upgrade. We watched a rep get a real-time prompt to slow down during a discovery call. Small moment, but those add up across 50 calls a day.
Grasshopper
If you just need a business number that rings your cell, don't overthink it. Grasshopper charges a flat $14/mo on the True Solo plan or $25/mo on Solo Plus when billed annually - no per-user pricing, no seat math. The Small Business tier runs $80/mo billed annually and covers multiple numbers and extensions.
It's deliberately simple. That's the point. A common recommendation in r/smallbusiness threads for exactly this reason. Skip it if you need CRM integrations or coverage outside the US and Canada.
RingCentral
The enterprise-grade option - and overkill for most teams reading this. RingCentral's Core plan runs $20/user/mo annually, $30 monthly, and packs in video, messaging, and phone. But Core caps SMS at 25 texts per user per month. That's unusable for outbound texting. You'll need Advanced at $25/user/mo on annual billing for 100 texts.
If you're scaling past 50 seats, RingCentral earns its spot. Under 10 seats? You're paying for features you'll never touch.
Aircall
Built for sales and support teams running call-heavy workflows. Native CRM and helpdesk integrations, solid call routing, and pricing starting at $30/license/mo billed annually.
The dealbreaker: a 3-license minimum. A 2-person team pays for a phantom third seat - $90/mo before a single call. Three or more reps? Aircall is genuinely good. The HubSpot and Salesforce integrations are among the cleanest we've seen in this category.
Quick Mentions: JustCall & Zoom Phone
JustCall is outbound-focused with a power dialer, SMS automation, and AI coaching on higher tiers. The Team plan starts at $29/user/mo with a 2-seat minimum, but the real value kicks in at Pro for $49/user/mo. Steep for basic calling.
Zoom Phone makes sense if your company already lives in Zoom. The base metered plan is $10/user/mo, but outbound calls cost per-minute on top. Unlimited calling plans run $15-$23/user/mo depending on the tier. For light internal calling, it works. For outbound-heavy teams, the per-minute charges add up fast.
Let's be honest: if your average deal size is under $10k and your team is fewer than 10 people, you probably don't need RingCentral, Aircall, or JustCall. Nextiva or Dialpad covers 90% of what small teams actually use, at half the price.
How to Switch Without Losing Your Number
1. Sign up with your new provider first. Don't cancel Quo until the port is confirmed live - canceling early can release your number back to the carrier pool. This is the single most common mistake we see.
2. Submit your Letter of Authorization to the new provider. They handle the port request with Quo's underlying carrier.
3. Expect 1-2 weeks. Keep both systems active during the transition. Yes, you'll pay for overlap. It's worth it.
4. Verify your contact data before loading it. Your new phone system handles the calls, but if your team is dialing dead numbers, the system doesn't matter. Prospeo verifies emails and phone numbers across 300M+ profiles with 98% email accuracy, so your reps reach live contacts instead of voicemails and disconnected lines.
If you’re building a more complete outbound motion, pair the switch with better sales prospecting techniques and a cleaner lead generation workflow so your new dialer isn’t just calling the same bad list faster.
Your new VoIP provider handles the calls. Prospeo handles who you call. 300M+ profiles, 30+ filters including buyer intent and job changes, and direct dials verified every 7 days. At $0.01 per lead, one connected call pays for thousands.
Pair your new phone system with numbers that actually pick up.
FAQ
Is Quo the same as OpenPhone?
Yes. OpenPhone rebranded to Quo after raising $105M in funding. The platform, core features, and pricing tiers remain the same. The rebrand reflects an expansion into AI-powered call handling via the Sona agent, but existing functionality hasn't changed.
Will Quo raise prices after the rebrand?
No official announcement yet, but the $105M raise creates real pricing anxiety - existing users on Reddit aren't shy about saying so. Most VoIP ports complete in under two weeks, and many users aren't waiting to find out.
How long does porting a number from Quo take?
Typically 1-2 weeks. Submit your LOA to the new provider first and keep Quo active until the port is confirmed live. Canceling early risks releasing your number back to the carrier pool permanently.
What's the cheapest Quo alternative for a solo founder?
Grasshopper's True Solo plan at $14/mo billed annually is the most affordable option with no per-user pricing. If you also need verified contact data for outbound prospecting, Prospeo's free tier includes 75 email lookups and 100 Chrome extension credits per month - no credit card required.
