VoIP phone service for business: a VoIP phone system for small teams

VoIP phone service (Voice over Internet Protocol) makes and receives phone calls over an internet connection instead of a traditional phone line. The call is converted to data, sent over the internet, and delivered to any ordinary phone number. To the person you call, it is simply a phone call.

Business VoIP typically costs $15 to $40 per user per month in the US, with unlimited domestic calling usually included. Phoner starts at $15 per user per month on Starter and $29 on Team, billed yearly, with no hardware to buy. Extra numbers are $5 per month each.

No. VoIP works on the phones and computers you already own, through an app or a browser tab. Desk phones (SIP handsets) still exist and still work if your team prefers them, but they are optional. Most small teams never buy one.

About 100 kbps of upload and download per simultaneous call, which is a tiny fraction of any modern broadband connection. A five-person team on a single call each needs roughly 0.5 Mbps. Stability matters more than raw speed, so a wired connection helps.

Usually yes, for a business. A traditional business line runs roughly $40 to $70 a month per line and bills long distance separately, while VoIP is $15 to $40 per user with unlimited US and Canada calling included, no PBX hardware, and no install visit.

No, not on its own. VoIP depends on your internet connection and your device, so a power cut that takes down your router takes down the line. Calls can be set to forward to a cell number automatically, which is how most teams cover it.

Yes. Number portability is a legal right in the US, so you can bring your existing business number to a VoIP provider. Phoner ports numbers in for free, it takes one to two weeks, and your current line keeps ringing until the moment the port completes.

Yes. Interconnected VoIP providers in the US are required to deliver 911 calls, but they route them using the service address you register rather than live location data. Keep that address current, and when you are away from it, call 911 from a mobile phone instead.

Business VoIP calls are encrypted in transit by any credible provider, which is more protection than a traditional phone line ever offered. The realistic risks are account takeover and toll fraud, not eavesdropping, so the security that matters most is strong passwords, two-factor authentication, and admin permissions.

An internet connection and a device you already own. The apps on iOS, Android, desktop, and the browser act as the phone, so most small teams buy nothing at all. SIP desk handsets and headsets still work if your team prefers a physical phone on the desk.

VoIP is the technology, the method of carrying a call over the internet. A VoIP phone service is the product built on top of it: the number, the phone menu, the ring groups, the voicemail transcription, and the support behind them. You can think of VoIP as the engine and a VoIP phone service as the whole car. Phoner is the service; VoIP is how it works.

Judge providers on four things, not on feature lists. Is the price per user and month to month rather than a multi-year contract? Is number porting free? Is E911 supported, and is registering your address simple? And does the plan you are actually quoted include the auto attendant, ring groups, and call recording you need, or are those an upsell to a higher tier? A provider that answers those four plainly is usually the honest one.

Sign up, choose a new number or start a free port of the one you publish, build your menu and ring groups in the browser, and have your team install the apps. Keep the old line active until the port completes, which takes one to two weeks, so nothing goes dark during the switch. The whole setup takes minutes of actual work; the porting is the only part that waits on a timeline outside your control.

For the overwhelming majority of businesses, yes. The FCC counts 83.7 percent of US business voice lines as VoIP as of June 2025, so it is already the mainstream choice, not the risky one. The single real vulnerability is that VoIP needs power and internet, so a blackout takes the line down. The standard mitigation is automatic forwarding to a cell number, which you should configure on day one.
