Do I need special hardware or desk phones?

No. Modern VoIP runs over your internet connection through desktop and mobile apps, so you can make and take business calls on the devices you already own. Desk phones are optional and can be added if your team prefers them.

Can I keep my current business phone number?

In most cases yes - number porting is standard, and providers will transfer an existing number over. Porting can take from a few days to a couple of weeks, so keep your old service active until it completes.

What's the difference between a virtual number and a full VoIP phone system?

A virtual number (like Grasshopper or Google Voice) forwards calls and texts to phones you already have and is great for solo users and very small teams. A full VoIP system (like RingCentral or 8x8) adds real call handling - queues, multiple extensions, admin controls, and analytics - for teams that manage higher call volume.

How reliable is VoIP for calls?

Call quality depends heavily on your internet connection. A stable broadband connection with enough upload bandwidth generally delivers clear calls, but weak or congested Wi-Fi will cause dropouts. For critical use, a wired connection and a provider with a solid uptime record matter most.

Do these systems handle business texting (SMS)?

Many do, including OpenPhone, RingCentral, and Dialpad, but availability and message limits vary by plan and by country. If texting customers is central to your business, confirm SMS/MMS support and any per-message or monthly caps before you commit.

Best VoIP & Business Phone Software (2026)

A business phone system replaces desk phones and personal cell numbers with cloud-based calling, texting, and voicemail that work from an app on any device. Instead of buying hardware and paying a phone company for lines, you pay a monthly per-user fee for a business number, extensions, call routing, and features like auto-attendants, call recording, and SMS. For a small or mid-sized business, the payoff is looking professional (one main number, extensions, business hours), keeping work calls off personal phones, and giving a team the ability to route, transfer, and track calls without an on-premise PBX.

The right pick depends less on brand and more on how you actually use the phone. A solo founder or side business mostly needs a second line and a clean voicemail; a sales or support team needs dialers, call queues, and CRM integrations; a growing company needs reliable uptime, admin controls, and room to add seats. Video and team chat may already be covered by tools you own, so an all-in-one 'unified communications' suite is not always the best value.

Start by counting your users, listing must-have integrations (CRM, help desk, Google Workspace), and deciding whether you need real inbound call handling or just a professional number. Then check contract terms, per-user pricing at your seat count, and whether the features you need are on the base tier or locked behind an upgrade.

Our top VoIP & Business Phone picks

What to look for

Per-user pricing at your real seat count, and whether it's month-to-month or an annual contract - the advertised price is often the annual rate
Which features are on the base plan vs. gated behind higher tiers (call recording, auto-attendant, SMS, analytics, and integrations are common upsells)
Integrations that matter to you - CRM, help desk, and Google Workspace or Microsoft 365 - and whether they're native or require add-ons
Call handling depth: auto-attendants, call queues, business-hours routing, and a visual flow editor if your call paths are complex
Reliability and support - uptime track record, whether support is included, and how you reach a human when calls drop
SMS/MMS and international calling if you text customers or call across borders, since these are frequently metered or extra
