Phone Lines

The foundation of business voice communication.

Updated yesterday

What is a phone line?

A phone line is the connection that enables voice communication—whether through traditional copper wires or modern digital networks. For businesses, phone lines remain a critical part of daily operations, supporting customer calls, conferencing, and team communication.


Types of phone lines for business

  1. Analog (POTS)

    • The original copper-based “Plain Old Telephone Service.”

    • Reliable for basic calling but limited in features.

    • Commonly found in small offices or as backup lines.

  2. Digital

    • Uses digital signals for clearer quality and more flexibility.

    • Two common types:

      • ISDN (Integrated Services Digital Network) – An older digital standard that supports voice, video, and data.

      • VoIP (Voice over Internet Protocol) – Today’s leading choice for businesses. Runs over the internet, often at lower cost, and integrates with advanced phone system features.


Why businesses are shifting to VoIP

  • Cost savings – No need for traditional copper infrastructure.

  • Scalability – Add or remove lines as your team grows.

  • Advanced features – Call routing, voicemail-to-email, analytics, and more.

  • Flexibility – Use desk phones, mobile devices, or softphone apps.


Choosing the right option

  • Analog works for basic calling or fax lines.

  • VoIP is the best fit for most businesses, offering modern features and long-term flexibility.

  • ISDN is largely legacy and being phased out in favor of IP-based systems.
