1. RingCentral — Best overall all-in-one
RingCentral is the most popular cloud phone system for a reason — it does everything. Its RingEX platform combines business calling, SMS, team messaging, video meetings and fax in one app, backed by a 99.999% uptime guarantee and 300+ integrations including Salesforce, Microsoft 365 and Google Workspace. If you want a single, reliable system that scales from a handful of users to thousands, RingCentral is the safe default.
2. Nextiva — Best for customer service
Nextiva pairs a rock-solid business phone service with a full customer-experience platform, bringing voice, video, SMS, live chat and social messaging into one place. It’s known for excellent US-based support and reliability, making it a favourite of small and mid-sized businesses that talk to customers all day. Built-in call routing, analytics and AI tools help teams handle high call volumes without a separate contact-center product.
3. 8x8 — Best for global teams
8x8 is built for businesses that operate across borders. Its higher tiers include unlimited calling to dozens of countries, and it blends a cloud phone system with contact-center features in a single platform. With strong international coverage, detailed analytics and broad compliance certifications, 8x8 is the pick for distributed teams and companies with overseas customers or offices.
4. Dialpad — Best AI features
Dialpad puts artificial intelligence at the centre of every call. Its Ai Voice technology transcribes calls in real time, surfaces live coaching prompts, and automatically writes call summaries and action items the moment you hang up. If you want a modern, AI-first phone system — especially for sales and support teams — Dialpad is the most innovative option here, and it’s competitively priced.
5. Zoom Phone — Best if you already use Zoom
If your team already lives in Zoom, adding Zoom Phone is a no-brainer. It bolts a full cloud phone system onto Zoom Workplace, so calling, meetings, chat and whiteboard all share one familiar app. Pricing is among the most flexible here — you can pay per user or per line — and call quality is excellent. It’s the natural choice for Zoom-centric and hybrid teams.
6. Ooma Office — Best value for small business
Ooma Office is designed for small businesses that want professional phone features without complexity or contracts. Setup takes minutes, plans are affordable, and you still get a virtual receptionist, ring groups, mobile and desktop apps, and call recording on higher tiers. For shops, clinics and small offices that just need reliable calling and a few smart features, Ooma is the best-value pick.
7. Grasshopper — Best for solopreneurs
Grasshopper isn’t a full phone system — it’s a virtual business phone line that runs on top of the phone you already own. Pick a local, toll-free or vanity number, then take business calls and texts through an app while keeping your personal number private. With flat-rate pricing (not per user), it’s ideal for solopreneurs, freelancers and very small teams that want to look professional without buying hardware.
What to Look for in a Business Phone System
The market has fully shifted from traditional landline PBX hardware to cloud-hosted VoIP. A modern hosted cloud phone system needs no on-site equipment, scales instantly as you add staff, and is far cheaper to run. Here’s what matters when comparing providers:
- Core calling features: unlimited domestic calling, an auto-attendant/IVR, call routing and queues (ACD), voicemail-to-email and call recording.
- Unified communications: the best systems fold in team messaging, SMS, and video meetings so your whole team works from one app.
- Mobile & desktop apps (softphones): make and take business calls from a laptop or phone — essential for remote and hybrid teams.
- Integrations (CTI): connections to your CRM, helpdesk and Microsoft 365 or Google Workspace so calls log automatically. If you track marketing calls, pair this with call tracking.
- Reliability: look for a published uptime SLA (99.99%+) and a plan for internet outages.
- Pricing & scalability: most cloud systems charge per user per month, so costs grow predictably as you hire.
- Advanced tools: call analytics, AI transcription, and an auto-dialer or predictive dialer for outbound sales teams.
Frequently Asked Questions
What is a business phone system?
A business phone system is the technology that handles your company’s calls. Today that almost always means a cloud-based VoIP system, which carries calls over the internet and adds features like an auto-attendant, call routing, voicemail-to-email, texting, video meetings and CRM integration — all managed through an app rather than physical hardware.
How much does a business phone system cost?
Most cloud VoIP systems charge per user per month, typically from around $15 to $30 depending on the features and number of users. Virtual-line services for solopreneurs (like Grasshopper) use a flat monthly rate instead. Higher tiers add things like unlimited international calling, advanced analytics and contact-center features.
Is VoIP better than a traditional landline for business?
For almost every business, yes. Cloud VoIP is cheaper, works from anywhere, scales instantly and includes modern features (video, SMS, AI transcription, CRM integration) that landlines can’t match. Traditional PBX hardware now makes sense only in niche cases with very specific reliability or regulatory requirements.
What is the best business phone system overall?
RingCentral is the best all-in-one choice for most businesses thanks to its reliability and feature depth. Nextiva is excellent for customer service, Dialpad leads on built-in AI, Zoom Phone is ideal if you already use Zoom, and Ooma Office and Grasshopper are the best picks for small businesses and solopreneurs respectively.
Do I need special desk phones or hardware?
No. Every system here works through softphone apps on your computer and smartphone, so you can be up and running without buying any hardware. Physical desk phones are optional — useful for reception desks or call centres — and most providers sell or support compatible IP phones.
Can I keep my existing business phone number?
Yes. All of these providers support number porting, so you can bring your current business numbers with you when you switch. Porting usually takes a few business days, and providers give you a temporary number to use in the meantime.
Final Thoughts
The right business phone system depends on your size and priorities. For a dependable all-rounder, start with RingCentral; choose Nextiva if customer service is your focus, Dialpad for cutting-edge AI, or Zoom Phone if your team already runs on Zoom. Smaller operations are well served by Ooma Office, while solopreneurs can look professional in minutes with Grasshopper. Most offer free trials, so shortlist two or three and test them with your own team before committing.
