Business phone line costs: business telephone line, business landline service and VoIP phone line prices per line

Between $10 and $35 per line per month in August 2026 for a cloud line with a published rate card, and $15 to $20 per line at the two incumbent carriers that publish a price. Spectrum lists $20 per line for twelve months when bundled, and Verizon One Talk starts at $15 per line. AT&T and Comcast publish no per-line price on their business phone pages. Taxes and regulatory surcharges are extra everywhere.

For one line, expect $15 to $35 a month all in. The low end is a cloud plan such as Phoner Starter or Nextiva Core at $15 per user billed annually. The high end is a carrier line at a default-configured account: Spectrum's $20 line plus the $10 payment processing charge for not being on Auto Pay and the $5 charge for not being on paperless billing comes to $35 before taxes. Enrolling in both removes $15 of that.

Pick a provider, choose or port a number, and connect it to a device. On a cloud provider that takes a few minutes and needs no visit: you sign up, search for a local or toll-free number, and answer calls from an app on a phone, laptop or desk phone. On a copper line from a carrier it means a quote, an install appointment and usually a term commitment. If you are keeping an existing number, order the new line first and port afterwards.

Only from a carrier on copper or fiber voice service, and that market is shrinking fast. A cloud business phone line runs over an internet connection by definition, though not necessarily a wired one: the apps work on cellular data, and a call needs only about 100 kbps in each direction, so a phone with signal is a working line. If you need voice service where there is genuinely no data connectivity, a traditional line or a cellular device is the answer.

No, and the difference is what people usually overpay for. A number is an identity you publish. A line is a path a call travels on, and on copper each line could carry exactly one call, which is why identity and capacity used to be the same purchase. On a cloud system they are separate: one published number can ring five people at once and hold a second caller without a busy signal, so most businesses need far fewer paths than they had lines.

Almost certainly not for the people, and possibly yes for the equipment. Voice service for staff moves to cloud lines cleanly. What does not always move is the analog hardware: alarm panels, elevator phones, fire alarm communicators, fax machines and some older card terminals. Inventory every device with a phone cord in it, decide for each whether it goes to an analog terminal adapter or a cellular communicator, and check local code for fire alarm equipment before cancelling anything.

Among providers publishing a rate card in August 2026, Google Voice Starter at $10 per user is the lowest headline figure, but it caps at ten users, has no auto attendant and no ring groups, and team plans require a Google Workspace subscription per user billed separately. Zoom Phone's metered plan is $10.50 billed annually. Grasshopper is $14 flat for the whole account rather than per user, which makes it the cheapest option for a solo business that wants two or three numbers.

Yes, and for a lot of one-person businesses that is the whole requirement. A cloud line adds a separate business number to the phone you already carry, with its own voicemail, its own business hours and its own caller ID, so personal and work calls stay apart on one device. That is what our Starter plan at $15 per user per month is. You do not need a second handset, a second carrier plan or a second SIM.

Count concurrent calls, not employees. Watch your call log for two weeks and find the busiest overlap: if you never have more than two calls running at the same time, you need two paths, whatever your headcount. Then count the identities you publish, such as a main number, a sales number and a toll-free number, because those are separate. Buying one line per person is the copper habit that makes this category expensive.

Yes. Number portability is a legal right in the United States, and under FCC rules a carrier cannot refuse to release a number in the same area because you owe a balance. Order the new line first, test it, then submit the port with a recent bill and the exact account name and address the losing carrier has on file, since a mismatch there is the usual cause of a rejected port. Keep the old line active until it completes. Porting into Phoner is free and typically takes one to two weeks.

No, though the FCC's own data shows that in American business the two have largely swapped places. A landline is an analog circuit over copper. VoIP carries the call as data over an internet connection. Of the roughly 53 million business wireline connections in the United States, 83.7 percent are already interconnected VoIP rather than switched access lines, so the question in most offices is no longer whether to move but what is still sitting on the old pair.

Neither company says. What we can report is what is on the pages: we read the AT&T Phone for Business page and the Comcast Business phone page in August 2026 and neither carried a dollar figure, so both price by quote. The practical consequence for a buyer is that you cannot compare those two against anything without a sales conversation, and that any figure you find quoted for them elsewhere came from someone else's quote rather than from a published rate.

Grandfathering means the carrier stops selling the service to new customers and starts a sunset, and since the FCC's March 2026 order it no longer requires an application to the Commission. You are entitled to keep the service for now. What the carrier must do is notify you, and under the new rule that notice has to include an approximate date by which it intends to seek to permanently discontinue the service and a statement about alternative services in your area. Treat the date in that letter as your migration deadline.
