Voice Over IP (VOIP)

VOIP Services

Voice over Internet Protocol (VoIP) is a type of technology that converts voice communications into digital data that is transmitted over the internet, or a packet-switched network. In layman's terms, VoIP allows you to make telephone calls using a high-speed internet connection instead of a traditional analog phone line.

The way calls are routed may be different with VoIP, but you still use your existing phone equipment as you would with a regular telephone line. Most VoIP phone system services provide a phone adapter that connects your existing home phone with the internet. You simply connect the adapter to your home internet network and home phone and start dialing. Calls can also be placed using an internet-connected smartphone or tablet through your VoIP provider’s proprietary app or a computer with speakers and a microphone.

While the technology may seem complicated, VoIP service is becoming an increasingly reliable and popular alternative for consumers and small businesses. VoIP phone systems can provide significant cost savings over a conventional phone system, with lower monthly fees and cheaper long distance and international rates. VoIP users are also privy to numerous calling features, ones that typically cost extra with regular phone services. And since you can use the phones you already have, setup costs are minimal.

VoIP Services: What to Look For

Knowing how VoIP services vary in terms of the service plans and features each service offers will help you choose the service that can best meet your needs. Consider the following key factors when seeking out the best VoIP provider for your home or office.

Service Plans

The service plans a VoIP provider offers and how much they charge for those plans will be a major deciding factor when you choose a service. VoIP service plans should be comprehensive and flexible so you can make as many calls as you want without worry of racking up hefty charges. Look for plans that include unlimited minutes, select international calls and the ability to keep your existing phone number when you sign up. VoIP providers should also offer additional services that you can sign up for, which are ideal for business users. These include the ability to add additional lines, sign up for a toll-free number, and send and receive faxes using the service.

Calling Features

Basic calling features such as voicemail, caller ID and conference calling should be included with any VoIP phone plan. The best VoIP services provide these as well as enhanced calling features like 411 directory assistance, call transfer and e911. The latter is a useful feature that automatically transmits your geographic location and name to emergency responders in the event you are unable to convey that vital information yourself.

Ease of Setup

Switching from regular phone lines to VoIP phones shouldn’t be complicated or require a steep learning curve. VoIP services should be easy to install, supplemented with comprehensive and easy-to-understand setup instructions.

Help & Support


An easy setup doesn’t necessarily mean you won’t encounter issues or have questions when using your VoIP system. Thus, first-class help and support options are a must. VoIP services should provide live customer support via telephone and email, as well as standalone documentation online, such as FAQs and a knowledgebase, that you can reference as needed. VoIP discount plans are a more affordable and feature-rich alternative to a traditional phone line. Whether you are looking to cut costs or get more from your phone service, VoIP presents a viable solution for your telecommunications needs.
