VoIP vs Landline
Landlines are dying. AT&T is shutting down copper. Here is why VoIP wins on every metric that matters for your business.
What Is a Landline?
A landline — also called a POTS (Plain Old Telephone Service) line — is a traditional phone system that transmits voice over copper wires physically connected from your building to the telephone company’s central office. This technology has been the backbone of business communication since the late 1800s.
How It Works
Copper wires run from your office to the local telephone company switch. Analog voice signals travel over these dedicated copper pairs. Each phone line requires its own physical copper connection, and features like voicemail, call waiting, or caller ID are add-on services billed separately. The system requires an on-premises PBX (Private Branch Exchange) box if you need multiple extensions, and a technician must come on-site for any changes to your phone setup.
Advantages
- Works during power outages — copper carries its own low voltage
- Familiar technology that every employee already knows how to use
- Does not require internet connectivity
- Extremely reliable call quality on dedicated copper circuits
Disadvantages
- Expensive — $45 to $75 per line per month, plus long-distance charges
- Very limited features compared to modern phone systems
- Tied to a physical desk in a physical office
- AT&T, Verizon, and major carriers are sunsetting copper infrastructure
- Scaling requires a technician visit at $100+ per line
- No integration with email, CRM, or business applications
What Is VoIP?
VoIP (Voice over Internet Protocol) is a phone system that transmits voice calls over your existing internet connection instead of copper wires. Your voice is converted into digital data packets and routed over the internet, the same way email and web traffic travel. VoIP has become the standard for modern business communication.
How It Works
VoIP converts your voice into digital data and sends it over your internet connection to the recipient. You can make and receive calls from a desk phone, computer softphone, or mobile app — all using the same business number. The system is hosted in the cloud, so there is no on-premises PBX hardware to maintain. Adding users, changing call routing, and configuring auto-attendants can all be done from a web dashboard in minutes. Most VoIP providers deliver HD voice quality that actually sounds better than traditional landlines.
Advantages
- 60% cheaper than landlines — $19.99 to $29.99 per seat per month
- 50+ features included: auto-attendant, call recording, voicemail-to-email, video conferencing
- Mobile app lets you use your business number from anywhere
- Scales instantly — add or remove users online in minutes
- Full remote work support with the same number and features
- Integrates with CRM, email, calendar, and industry-specific software
- HD voice quality that exceeds traditional phone clarity
Disadvantages
- Requires a reliable internet connection (25 Mbps+ recommended)
- Slight learning curve for employees switching from traditional phones
- Power outages require a battery backup or cellular failover for continuity

Which Phone System Is Right for Your Business?
We believe in giving you the honest answer. There are still a few situations where a landline makes sense.
When Landline Still Makes Sense
- Locations with no reliable internet service available
- Elevator emergency phones required by building code
- Alarm systems that still require copper POTS lines (though most now support cellular)
- Locations where power outages are frequent and battery backup is not feasible
When VoIP Is the Clear Winner
- Any business with a reliable internet connection
- Teams with remote or hybrid workers
- Businesses with multiple locations that need unified communications
- Companies that need advanced features like auto-attendant, call recording, or CRM integration
- Cost-conscious businesses looking to cut phone bills by 60%
- Growing companies that need to add phone lines quickly without technician visits
The Copper Sunset
The landline as you know it is being decommissioned. Major carriers are shutting down copper POTS infrastructure across the country.
AT&T, Verizon, CenturyLink, and other major carriers are actively decommissioning copper telephone infrastructure nationwide. The FCC’s Order 19-72 authorized carriers to retire copper networks with proper notice. If your business still relies on copper POTS lines, you will eventually be forced to switch — and the transition will happen on the carrier’s timeline, not yours.
The bottom line: if you are still on copper POTS lines, you will be forced to switch. The only question is whether you switch now on your terms — with time to plan, test, and train — or later under pressure when your carrier sends the discontinuation notice.
Switching Is Easier Than You Think
Most businesses are fully migrated to VoIP in under two weeks with zero downtime during the transition.

VoIP vs Landline FAQ
No. Modern VoIP uses HD voice codecs that actually deliver better audio quality than traditional landlines. The key is having a stable internet connection with sufficient bandwidth. With a business-grade connection of 25 Mbps or higher, VoIP call quality will meet or exceed what you are used to with a landline. We test your connection before deployment to ensure there are no quality issues.
VoIP systems have built-in failover options for internet outages. Calls can be automatically forwarded to mobile phones, a secondary internet connection, or voicemail when your primary internet goes down. Most VoIP providers also offer cellular failover devices that switch to a 4G/5G connection automatically. With these backup measures in place, your effective uptime matches or exceeds traditional landlines. Your mobile app also continues to work on cellular data regardless of your office internet status.
Yes. Number porting is a standard part of every VoIP migration. We transfer your existing business phone numbers — including fax numbers — to the new VoIP system. Your customers, vendors, and partners continue calling the same numbers they always have. The porting process typically takes 7 to 14 business days, and we keep your old service active until the port is complete so you never miss a call.
Yes. Business-grade VoIP systems use TLS (Transport Layer Security) and SRTP (Secure Real-Time Transport Protocol) encryption to protect your calls. This is actually more secure than traditional landlines, which transmit unencrypted analog signals over copper that can be physically tapped. Modern VoIP platforms also meet HIPAA compliance requirements for healthcare organizations, making them suitable for sensitive communications. We configure network security best practices including VLAN segmentation for voice traffic.
Most businesses are fully migrated in 1 to 2 weeks. The system configuration and equipment setup can be done in a few days. The longest part is usually the number port from your current carrier, which takes 7 to 14 business days. During the porting window, we set up temporary call forwarding so you never miss a call. Your team can start using the new system (with temporary numbers) while the port processes. Employee training typically takes less than an hour — the systems are designed to be intuitive.
Not necessarily. You have several options: use VoIP desk phones (we recommend Yealink or Poly for best quality), use softphone applications on your existing computers, or use mobile apps on your smartphones. Many businesses use a mix — desk phones in shared spaces like reception and conference rooms, and softphone or mobile apps for individual employees. This hybrid approach minimizes hardware costs while maximizing flexibility. If you do want desk phones, quality IP phones start around $80 per unit.
