How does internet phone service work?

Internet phone systems use Voice over Internet Protocol (VoIP) technology to deliver voice communications and other multimedia through the internet. When you make an internet call, your voice is transmitted from the phone and is then digitized into data packets. Each data packet is sent over the internet to a specific destination and reconverted back to voice to complete the call. A VoIP internet call sounds exactly like a traditional landline call, thanks to advancements in digital and telecommunications technology.

How is VoIP used?

With Voice Over Internet, phone calls can be routed through any internet connection, even Wi-Fi®, and to other phone systems including landlines or cell phones. Did you know that the phone service that many cable companies throw into a bundle is often internet phone service?

VoIP technology can be implemented anywhere with an internet connection, allowing for a wide variety of uses.

In the home, internet phone service subscribers can place and accept calls just like they would with a standard landline service. Thanks to advancements in technology, VoIP can be implemented in several ways:

  • VoIP phones: These are digital phones that are connected to your home’s hardwired Ethernet or Wi-Fi® connection.
  • VoIP adapter: Homeowners can also use a VoIP adapter that converts their traditional analog home phones into an internet phone.
  • Smartphone: Internet phone providers like Ooma allow users to place calls through a mobile app you download on your cell phone., giving mobile VoIP access wherever there is a Wi-Fi® connection.

With increased internet bandwidth, businesses are also using VoIP technology into their offices. Companies of all sizes appreciate not having to maintain and house a PBX system on their premise. Plus, a VoIP system is easy to use and add new lines as companies grow. The technology is similar to VoIP home phone service, with a few key differences:

  • Single network use: Both data and voice controls can run over a single network, which helps companies of all sizes cut down on infrastructure costs.
  • Softphones: Businesses can use the internet phone features with software on a networked computer that shows a dashboard and a dial pad.
  • Unified communications: VoIP solutions allow businesses to treat all communications under one handset. This can include phone calls, fax, voicemail, videoconferencing and more.
  • Dual-mode phones: As the workforce becomes increasingly mobile, voice over internet protocol technology has bridged the gap between smartphones and desk phones with Wi-Fi® networks. This simplifies communications with fewer devices to manage, and less maintenance and upgrades to plan and execute.

Two reasons to get an internet phone system

Both homeowners and business owners cite two major reasons why they switched from traditional landline phones to VoIP: affordability and more features.
