Best PBXPlus Alternatives for Teams That Need a Proven Phone System
You're paying $14.99/user/month for a phone system with eight total reviews across every major platform. That's not a pricing problem - it's a trust problem. When your entire phone infrastructure depends on a tool almost nobody's reviewed, it's time to look at PBXPlus alternatives that thousands of teams have actually stress-tested.
Why Teams Leave PBXPlus
PBXPlus isn't bad. The features are solid for the price: IVR, a visual call flow builder, virtual numbers in 48+ countries, integrations with HubSpot, Zoho CRM, and Freshsales, plus the ability to bring your own carrier including Twilio.
The issue is risk.
Across G2 (4.1/5, 4 reviews), Trustpilot (4.0, 3 reviews), and Capterra (5.0, 1 review), PBXPlus has a grand total of 8 reviews. That's not a user base - it's a dinner party. We couldn't find any useful Reddit sentiment about PBXPlus or 500apps either, which reinforces just how thin the community is. The few reviews that exist are positive, but there's nobody to lean on when something breaks.
Then there's the 500apps lock-in. PBXPlus lives inside the 500apps Infinity Suite - 50 apps for $14.99/user. Sounds great until your phone system, CRM, and project management all share a single vendor. If 500apps changes direction or has an outage, everything goes down together.
Our Top Picks
- Best for sales teams: JustCall - AI call scoring, power dialer, 100+ integrations. From $29/user/mo.
- Best for SMBs on a budget: Nextiva - unified comms from $15/user/mo, basically matching PBXPlus's $14.99 price with far more reviews behind it.
- Best for simplicity: OpenPhone (now Quo) - calls + texts, zero bloat. From $15/user/mo.
Switching phone systems won't fix low connect rates - bad data will. Prospeo gives your reps 125M+ verified mobile numbers with a 30% pickup rate, so every dial on JustCall, Nextiva, or CloudTalk actually reaches a real person.
Stop burning dials on dead numbers. Start connecting at 30% pickup.

The Best PBXPlus Alternatives Compared
JustCall
Use this if you're running outbound sales and need a dialer, AI coaching, and deep CRM integration out of the box.
Skip this if you just need basic inbound call routing for a small office.
G2 names JustCall the best overall PBXPlus alternative, and we've seen why firsthand. The platform covers phone numbers in 70+ countries, includes power and predictive dialers on the Pro plan ($49/user/mo), and layers in AI call scoring and sentiment analysis at Pro Plus ($89/user/mo). Over 100 integrations mean it plugs into whatever CRM and sequencer you're already running.
The Team plan at $29/user/mo includes unlimited inbound and outbound minutes, AI transcription, and 500 SMS segments - all under a fair usage policy. That's double PBXPlus's price, but you're getting a tool with far more real-world usage behind it. Minimum 2 seats on all plans.
Nextiva
Nextiva is $15/user/mo versus PBXPlus at $14.99/user/mo, but with a user base that dwarfs it. The Core plan gets you business phone and team messaging. The Engage tier ($25/user/mo) adds up to 2,000 toll-free minutes and 500 text messages per user/month. AI features are available as paid add-ons beyond the base plan.
In our experience, the integration limitation is the real dealbreaker for some teams. Nextiva supports about 19 third-party integrations. If your stack runs on Salesforce, Outreach, and five other tools, that's going to feel restrictive. For teams building a broader RevTech stack, that constraint matters. For teams that live mostly inside Nextiva's ecosystem, it's a non-issue.
OpenPhone (Quo)
OpenPhone rebranded to Quo in September 2025, so you'll see both names around. The product is the same - a clean, simple business phone system built for small teams that want calls and texts without learning a complex platform. Not the right pick if you need advanced IVR, call queues, or 24/7 support.
Starter runs $15/user/mo on annual billing. Watch the add-ons: extra numbers cost $5/month each, international calling bills by destination, and there's a $1.50-3/month messaging fee per user. A 5-person team with 3 extra numbers ends up closer to $100/month than the $75 you'd expect. Still reasonable, but model it before you commit.
CloudTalk
CloudTalk shines for international teams. Local numbers in 160+ countries, unlimited US/Canada calling, and SOC 2/GDPR/HIPAA compliance badges that PBXPlus doesn't offer. Starts at ~$19/user/mo on annual billing. Power dialers and branded caller ID are available as add-ons, not included in base plans - budget accordingly.
If you're comparing dialers specifically (not just VoIP), it's worth scanning our breakdown of CRM dialer alternatives too.
GoTo Connect
Free calling to 50 countries, unlimited auto attendants, 99.999% reliability, and video meetings for up to 250 participants. The feature set is strong. The problem? You can't see what it costs without talking to sales. Estimates put the Phone System tier around $26/user/mo and CX at $34/user/mo. If you're mid-market and don't mind the sales dance, it's worth a quote.
Zoom Phone
If your company already lives in Zoom, adding Zoom Phone at ~$13/user/mo is the path of least resistance. It's solid for internal comms and basic inbound, but it isn't built for outbound sales teams - the dialer and automation features simply aren't there. If outbound is core, read up on what predictive dialing is before you choose.
Ooma Office
A straightforward office phone system starting at $19.95/user/mo. Good for brick-and-mortar businesses that need desk phones and basic routing, not for remote-first sales teams running outbound campaigns.
Also worth considering: RingCentral, Aircall, and Dialpad are solid options but priced higher and built for larger teams. If you have dev resources and want full control, open-source platforms like FreePBX exist - but they're a different beast entirely.
How to Pick the Right Replacement
Here's the thing: most teams overthink the phone system decision. The tool matters far less than the data you're feeding into it.
For a solo or micro team of 1-3 people, OpenPhone/Quo keeps it simple and cheap. Sales teams of 5-20 reps running outbound should go with JustCall - the dialer and AI coaching justify the premium. SMBs wanting unified comms will find Nextiva hard to beat at $15/user/mo. And if international coverage matters, CloudTalk's 160+ countries with built-in compliance is the clear winner.
One thing none of these tools fix on their own: bad contact data. Your phone system handles routing and call quality, but connect rates depend entirely on whether your reps are dialing real numbers. We've seen teams pair Prospeo's 125M+ verified mobile numbers with their dialer and hit 30% pickup rates - versus the industry average of roughly 12%. That gap shows up on day one. If you want to tighten the process end-to-end, start with BDR contact data benchmarks and a simple list quality QA workflow.
You just picked a phone system built for outbound. Now feed it data that performs. Prospeo delivers direct dials at $0.10/number with 98% email accuracy - refreshed every 7 days, not every 6 weeks like other providers.
Pair your new dialer with numbers people actually answer.
FAQ
Is PBXPlus shutting down?
No evidence of a shutdown. But with only 8 total reviews across G2, Trustpilot, and Capterra, and deep dependency on the 500apps ecosystem, adoption risk is real. If the broader suite loses momentum, PBXPlus goes with it.
What's the cheapest PBXPlus alternative?
Zoom Phone edges out the field at ~$13/user/mo if you already pay for Zoom. Nextiva Core and OpenPhone Starter both start at $15/user/mo - essentially matching PBXPlus's $14.99 price with far larger user bases and more community support.
How do I improve connect rates after switching?
The phone system handles routing and call quality, but connect rates live and die on data quality. Verified mobile numbers are the single biggest lever. Teams using verified mobiles consistently see 2-3x the pickup rates of those dialing unverified lists, which means fewer wasted dials and more live conversations per hour.
Can I migrate my numbers from PBXPlus?
Most VoIP providers support number porting. JustCall, Nextiva, CloudTalk, and GoTo Connect all handle inbound port requests - typically completed within 5-10 business days. Confirm with your new provider before canceling PBXPlus to avoid any gap in service.
