Business landline phone service

What business landline service means now

"Landline" now covers three different things: a traditional copper line from the local phone company, a digital voice line from a cable or fiber company (Spectrum calls its Business Voice a digital phone service), and cloud VoIP that rings over your internet connection. All three give you a business number that rings at your desk. They differ in what happens in an outage, how 911 finds you, and price.

Backup power and outage rules from the FCC (network upgrades page; VoIP and 911); 911 rules from 47 CFR 9.11; Spectrum from its Business Voice price guide; VoIP prices from the comparison.

What a business landline costs

Spectrum is one of the few phone companies that publishes business voice prices. Its price guide lists the Unlimited Local and Long Distance package at $50 a month for a first line, or $30 a month for months 1 to 12 and $40 from month 13 on the current promotion, plus $99 installation per location (price guide). Its sales page advertises $20 a line for one year when bundled with Spectrum Business Internet, with taxes and fees extra (Spectrum); an FAQ on the same Spectrum page says there are no contracts or added taxes, so ask which applies.

A cloud system's entry plan costs less per line and includes apps for each person's cell phone. The full breakdown is in VoIP vs landline and business phone system pricing.

Year one: one landline vs one cloud user

Before taxes and fees. Spectrum from its price guide; VoIP prices from each company's pricing page. A cloud plan covers one user with apps; a landline covers one line at one address.

Copper retirement: what the FCC rules say

Local phone companies are replacing copper with fiber. Under FCC rules, a copper retirement means removing or disabling copper loops, or replacing them with fiber-to-the-home or fiber-to-the-curb loops, and the incumbent phone company must give public notice of it (47 CFR 51.325).

• The notice periods. The incumbent phone company must serve its public notice on carriers that connect directly to its network and on 911 service providers, at least 90 days before a planned copper retirement, 15 days if the copper serves no customers, and 10 days for a short-term network change (47 CFR 51.333).
• Updated October 15, 2026. FCC amendments to section 51.333 and related network change and discontinuance rules took effect on October 15, 2026 (Federal Register). The 90, 15 and 10 day periods above are in the amended text.
• The rulemaking. The amendments come from the FCC proceeding titled Reducing Barriers to Network Improvements and Service Changes, Accelerating Network Modernization (WC Docket Nos. 25-208 and 25-209, FCC 26-19), first published April 20, 2026. Besides 51.333, they cover sections 51.329, 63.60, 63.62(a), (b) and (d), 63.63, 63.71 and 63.602 of the network change and discontinuance rules.
• You may not get a letter about the rule itself. The FCC says its rules do not require providers to notify retail customers directly about copper retirement, but providers will contact you if they need access to your premises to install new equipment (FCC).
• Service cuts are different. If a provider plans to discontinue, reduce or impair your service, the FCC says it must notify customers directly.

What copper retirement means for a business

If you get a notice

1. Note the date of the change and what it affects: copper retirement, a network change, or a cut in service.
2. List everything on the line: phones, alarm panel, fax, card terminal, elevator or gate phones.
3. Ask the provider what replaces the line, whether it needs power at your site, and whether a backup battery is offered.
4. If you plan to leave, start the port to a new provider before the change date and keep the old line until it completes.
5. Update the 911 address for every phone on the new service.

Backup power on lines that are not line-powered

When service is not powered over the phone line, the FCC requires the phone company to tell new customers at sale, and all customers every year, that they need backup power for the phone to work in an outage. At sale it must also offer a battery with at least 24 hours of standby power and explain what happens without one (FCC).

911 on business lines: Kari's Law and RAY BAUM'S Act

The FCC's dispatchable location rules cover landlines too: providers of fixed telephony service must provide automated dispatchable location with 911 calls (FCC). The rules were adopted on August 1, 2019 and took effect January 6, 2020. For multi-line systems, makers and vendors must pre-configure direct 911 dialing, and installers, managers and operators must make sure it works.

For internet phone service, 911 is a mandatory feature: customers cannot opt out, the provider must get your physical location before service starts, and every customer must acknowledge that they understand the limits of VoIP 911 (FCC).

Kari's Law applies to the phone system, not the wire: a multi-line system on copper lines needs direct 911 dialing and notification just as a cloud system does, if it was made, sold or installed on or after February 16, 2020.

Keeping your landline number when you switch

Numbers can move between landline, internet and wireless providers. Your old carrier cannot refuse the port even if you owe money, and simple ports should take one business day (FCC). Start the port with the new provider and keep the landline until it completes. The steps are in how to get a business phone number.

Switching off a landline, step by step

1. Pick the new provider and start a trial with a temporary number.
2. Test any equipment that uses the line (alarm panel, fax, card terminal) on the new service.
3. Start the port with the new provider; keep the landline active.
4. Register the 911 address for each phone, including suite or floor.
5. Cancel the landline only after the port completes and calls ring on the new system.

How to choose business landline service

• One line for an alarm, elevator or fax: keep a line, check whether it is copper or digital, and ask about backup power.
• A shop or office with one or two people: compare a single line with a per-user cloud plan; the cloud plan adds apps and a phone menu.
• Several people sharing a number: a multi-line cloud system costs less per person than separate lines.
• Locations with weak internet: a landline or digital voice line avoids depending on your router.

Questions to ask your phone company

• Is my line copper, digital voice or fiber? It decides which outage and backup power rules apply.
• Is it line-powered? If not, the company must offer a backup battery with at least 24 hours of standby at sale.
• Is copper retirement planned in my area? The phone company must give public notice before retiring copper.
• What happens to my alarm, fax or elevator line? Ask the equipment maker whether it works on the new service, and test it.
• What is my contract term and early termination fee? Porting cannot be refused, but contract fees still apply.

911 rules if you move to VoIP

From 47 CFR 9.11 and the FCC's VoIP and 911 guide. The difference is explained further in what a VoIP number is.
