POTS Replacement

Are you spending too much on your legacy phone’s repair and maintenance costs? Or are your Plain Old Telephone Service‘s (POTS) features limiting your company’s growth?

Upgrading your business phone can feel overwhelming. Your POTS lines run across elevator phone lines, door entry intercoms, fire alarm panels, and more. But even before the U.S. government-mandated shift to new technologies in 2022, POTS replacement had already begun.

The popularity of wireless networks triggered the Federal Communications Commission to phase out copper line phones. In fact, the FCC reports the number of POTS lines in the U.S. declined from 122 million in 2010 to 41 million in 2019. In 2022, landline ownership further plunged below 30% from over 90% in 2004, according to Statista.

One big factor driving the transition is the high maintenance cost. Noise and scalability issues are also accelerating the conversion. Analog signals are prone to interference, resulting in hissing or crackling sounds. And unlike internet-based systems, landlines need hardware installations and upgrades to add capacity.

If you’re scouting for the best POTS alternative for your business, this guide is for you. We’ll walk you through three viable solutions to make the switch from traditional phones easier.

3 Alternatives to POTS

Let’s take a closer look at the top three replacement options for your old POTS, also called Public Switched Telephone Network (PSTN).

1. Voice over Internet Protocol (VoIP)

    VoIP converts a person’s voice into a digital signal carried over the internet. PSTN is prone to disturbance from nearby power lines or radio waves. At the same time, analog signals can weaken over long distances. VoIP is less susceptible to these electromagnetic interferences. Instead, network congestion can affect call quality.

    Benefits of VoIP:

    • Cost-effective: Data from Expert Market shows that the average monthly cost for an analog line rental is $50. Every extra line may cost you $25. In comparison, VoIP monthly fees average $20.
    • Feature-rich: VoIP allows call forwarding, auto attendants (automated answering service), and video conferencing. Plus, its voicemail-to-email feature turns calls into audio files and sends them straight to your inbox.
    • Scalable: VoIP uses your existing internet service. You don’t need physical hardware for each line. This means you can easily add or remove users as your business grows without installing more equipment.
    • Remote accessibility: VoIP supports work-from-home and mobile workforce setups.

    2. Cellular POTS replacement

      Cellular phones rely on wireless broadband networks — long-term evolution (LTE) or 4G and 5G. The voice captured by a mobile device turns into digital signals that travel to the nearest cell tower via radio waves. The call moves from tower to tower until it reaches the intended recipient. Unlike VoIP, though, users can only use phones to access cellular services.

      Benefits of cellular POTS replacement:

      • Reliable connectivity: Users can stay in touch even during internet outages as long as they’re within a telecommunication carrier’s service area.
      • Quick deployment: Mobile phones are portable, making them a great solution for staying connected on the go.
      • Ideal for remote locations: Because mobile devices don’t need cables, cellular communication works best where broadband internet is unreliable.

      3. Cloud-based phone systems

        A cloud-based solution incorporates VoIP into a service suite called “unified communications.” This capability allows devices with an internet connection to have call features. More importantly, cloud systems integrate with various business applications, offering more than just call handling.

        Benefits of cloud-based systems:

        • Fully hosted service: Instead of an on-site PBX system, a third-party provider offers cloud hosting services on a subscription basis.
        • Advanced features: Cloud telephony covers instant team messaging and file sharing. You also get AI-powered call analytics and customer relationship management (CRM) integration.
        • Disaster recovery: Cloud-based phone services store data in the cloud rather than in internal data centers, as VoIP systems do. This means users can recover information in case of disasters. Additionally, this solution can reroute calls instantly in case of an outage.

        What You Need to Know When Migrating From POTS

        Simplify your POTS line replacement process by taking this four-step approach.

        Audit your current infrastructure

          Identify where POTS lines exist in your workspace or building and list them down. Besides elevator phone lines, door entry intercoms, and fire alarm panels, copper lines can also operate:

          • Fax machines
          • PBX trunks
          • Modems
          • Security or boiler room alarms
          • Gate or pool emergency phones
          • Point-of-sale systems

          Next, determine which landlines should stay and which ones to migrate to digital solutions.

          Then, conduct user interviews to pinpoint the challenges your POTS replacement should address. Meet with your IT team to assess your current IT network. Additionally, check your infrastructure’s capacity to support high-performance digital communications.

          Have you asked your telecom firm whether it’s sunsetting its traditional POTS soon? Doing so now will help you gauge how much time you have left to plan for the shift. Take the chance to ask about any alternatives they may offer.

          Choose the right POTS replacement solution

            Based on your audit, decide whether to go with VoIP, cellular, or cloud. Some key factors to consider when selecting your POTS replacement are:

            • Network redundancy and failover mechanisms (or backup connections) for uninterrupted service
            • Compliance with your industry’s emergency and safety standards (like NFPA 72 for fire protection)
            • Compatibility with your legacy phones and alarm systems
            • Real-time remote monitoring
            • Transparent pricing

            Make sure to document any cost savings and productivity gains to help you create your business case for decision-makers.

            Plan for installation and training

              Pick a service provider who can co-develop a phased timeline that minimizes downtime. Get the vendor’s requirements to ensure you can prepare while preserving business continuity.

              Your team should then receive training to maximize the new system’s features and capabilities. Besides continuous monitoring, your provider should also extend ongoing support. Check if they have online video tutorials and guides for future reference.

              Test and optimize

                Test the new communication infrastructure to iron out any issues. Ensure call flows work as expected, including integrating old phones into the new system. See if redundancy measures like LTE backups operate smoothly.

                Shifting from the traditional POTS to modern systems can enhance productivity and save costs while aligning with regulations. After an overview of the migration process, let’s discuss why our solution is the most viable choice.
