Allo Alternatives: 7 Business Phone Systems Worth Switching To
Most "Allo alternatives" lists recommend whiteboard tools, a dead Google messaging app, or even an ISP. None of that helps if you need to replace Allo - the AI business phone system with a 4.6/5 on G2 across 205 reviews, used by 20,000+ small businesses.
Here are the actual phone system replacements worth evaluating in 2026.
Our Picks (TL;DR)
- Quo (formerly OpenPhone) - Closest 1:1 Allo replacement. Mobile-first, lower starting price, and comparable AI features once you're on the right tier.
- Dialpad - Best pick if you want an AI-first phone system and don't want to stitch together add-ons.
- Google Voice - Cheapest option if you're already on Workspace and need nothing fancy.
Why People Switch from Allo
Allo does a lot right - AI call summaries are genuinely useful, setup is fast, and CRM integrations work out of the box. But G2 reviews tell a consistent story about what pushes people out: call quality issues (lag, dropped calls, connection hiccups), painful number porting, and platform stability bugs. One review titled "No support and broken features" captures the frustration well. If your team relies on phone calls to close deals, even occasional instability is a dealbreaker.
Dropped calls are frustrating. Dialing disconnected numbers is worse. Before you switch phone systems, make sure your contact data is actually worth calling - Prospeo's 125M+ verified mobile numbers deliver a 30% pickup rate, and every record refreshes every 7 days.
Fix the data before you fix the dialer.
Pricing at a Glance
The "AI Included?" column is where the hidden costs live.

| Allo | $32/user/mo | Yes | 1 | Small sales teams |
| Quo | $15/user/mo | Business+ ($23) | 1 | Allo replacement |

| Google Voice | $17/user/mo* | No | 1 (cap: 10) | Budget pick |
| Aircall | $30/user/mo | +$9/license | 3 | Mid-market teams |
| Grasshopper | ~$15-$90/mo flat | No | N/A | Solopreneurs |

*Google Voice requires Google Workspace (~$7/user/month) plus a Voice license starting at $10/user/month, so $17/user/month in practice for the Starter tier.
Best Allo Alternatives in 2026
Quo (Formerly OpenPhone) - Closest Replacement
Quo is the most natural landing spot for teams leaving Allo. It rebranded from OpenPhone in September 2025, and the product is mobile-first in the same way Allo is - one number across all your devices, clean mobile app, business texting built in. We've seen a lot of teams make this switch with minimal friction.
Pricing runs $15/user/mo (Starter) to $35/user/mo (Scale) on annual billing, with a 7-day free trial. The catch: AI summaries are locked to the Business plan at $23/user/mo, and CRM syncing has known issues - webhook inconsistencies and integration reliability problems that break automated workflows. If your outbound sequences depend on clean CRM data flowing back from calls, test this thoroughly before committing.
Dialpad - Best Built-In AI
Dialpad is one of the strongest AI-native phone systems in the category, with transcription, summaries, and coaching features designed to live inside the dialer experience rather than bolted on later.
Pricing typically falls in the ~$15-$35/user/mo range depending on tier and billing. We've found the transcription quality genuinely strong - better than what you get from Allo's summaries in most side-by-side tests. The real-time coaching nudges during live calls are a nice touch that Allo doesn't offer at all.
Skip it if you're a mobile-first team. Dialpad's desktop experience is polished, but the mobile app doesn't feel as native as Allo or Quo. It's built for desk-based SDR teams, not field reps dialing from their cars. If you're comparing options, see our Dialpad alternatives breakdown.
Google Voice - Budget Pick (With Catches)
Google Voice looks cheap at $10/user/mo until you add the required Workspace subscription - so $17/user/mo in practice. It works fine for simple calling if you're already on Workspace and need a business number for under 10 people.
Here's the thing: call recording is gated to the $30/mo Premier plan, there are no toll-free numbers, and there's no native CRM automation. Google Voice is a phone number, not a phone system. For a two-person startup that just needs to look professional on outbound calls, it's fine. For anyone running a real sales prospecting motion, you'll outgrow it in a month.
Aircall - Mid-Market (Watch the Add-Ons)
Aircall starts at $30/user/mo on annual billing with a 3-seat minimum, so you're paying $90/mo before you've done anything. Add AI summaries at $9/license and analytics at $15/license, and a 5-person team hits $3,240/year. Worth it for 10+ rep teams that need proper call center routing and monitoring. Overbuilt and overpriced for everyone else.
The Aircall integrations page shows 100+ native connections, which is genuinely impressive if your stack is complex. But if you're a 3-person team running HubSpot, you don't need 100 integrations - you need one that works reliably. (If you're doing deeper vendor comparisons, our Aircall vs CloudTalk guide may help.)
Grasshopper - Simplest for Solopreneurs
Flat-rate plans from ~$15-$90/mo for anyone who just needs a professional phone line. No AI, no CRM integrations - just a business number that rings. If you're a solo founder who needs to separate personal and work calls, Grasshopper does that and nothing more. That's not a criticism.
RingCentral - Enterprise-Grade
Starts at ~$20-$35/user/mo, but the AI Receptionist module starts at $39/mo extra. RingCentral's feature comparison shows the full breakdown across tiers. Overkill for small teams, but worth evaluating if you need video, messaging, and phone on one platform with enterprise compliance requirements.
Hot take: Most teams switching from Allo don't need an enterprise platform. They need a $15-$25/user system that works reliably and doesn't drop calls. Quo or Dialpad will cover 80% of you.
Your connect rate isn't a phone system problem - it's a data problem. Teams using Prospeo's verified mobiles book 35% more meetings than Apollo users and pay roughly $0.01 per lead. No contracts, no sales calls, no stale numbers.
Stop burning dials on dead numbers.
How to Choose the Right One
Let's be honest - the phone system is rarely the real bottleneck for outbound teams. It's the data underneath. We've watched teams spend weeks evaluating dialers when their connect rates were tanking because 30% of their phone numbers were disconnected. If that sounds familiar, verify your contact list with a tool like Prospeo before burning cycles on platform demos.
Beyond that:
- Closest Allo replacement: Quo. Similar feel, lower starting price, 7-day trial.
- Best AI without add-on chaos: Dialpad. Strong AI-first experience, solid transcription.
- Tightest budget: Google Voice, but only if you're already on Workspace and your team is under 10 people.
The consensus on r/sales threads about phone systems is pretty clear: pick one that's reliable, don't overthink it, and spend your energy on the data and the pitch instead. If you're rebuilding your outbound motion, pair the dialer decision with a tighter cold calling system and better sales communication.
FAQ
Is Allo the same as Google Allo?
No. Google Allo was a messaging app discontinued in 2019. Allo, built by The Mobile-First Company, is an AI business phone system. G2's "Allo alternatives" page covers a different product category entirely, which is why it mixes in tools like Miro and Mural.
What's the cheapest alternative to Allo?
Google Voice at $17/user/mo total if you're already on Google's ecosystem. Grasshopper offers flat-rate plans from ~$15/mo for solopreneurs who don't need AI features.
How do I improve connect rates after switching?
The phone system is half the equation. If your contact data is outdated, you're dialing wrong numbers regardless of platform. Verify your list before launch week so you aren't wasting reps' time on disconnected lines.
Can I port my Allo number to another provider?
Yes, all major carriers and VoIP platforms support number porting. Quo and Dialpad both handle inbound ports within 1-3 business days. Start the port request before canceling Allo to avoid losing your number during the transition.
