What Is VoIP?

Also known as IP telephony, VoIP is a technology that transforms voice signals from the sender into small data packets, adds routing information, and transfers them to the receiver via Internet Protocol networks, such as the Internet. VoIP converts the sender’s voice into a digital signal, which means you can make a call from your computer, phone, and other devices.

VoIP sounds like a completely new thing, but it’s been around for a while. Some of the most common VoIP apps are WhatsApp, Google Meet, and FaceTime.

VoIP: A Brief History of VoIP

VoIP was created by a company called VocalTec around 1995 to help users save money on long-distance calls. VocalTec made the first Internet phone to contact each other via connected speakers and microphones. VocalTec continued to enhance its product through 1998. After 2000, communication companies started adding VoIP capabilities to switches and software. And by 2003, VoIP was so popular that 25 percent of all voice calls were based on VoIP.

What Is Wholesale VoIP and What Does It Mean to Sell VoIP?

A wholesale VoIP offering is where a VoIP carrier sells large volumes of voice communications to other smaller service providers, which allows them to resell VoIP calls on their platforms to end-users.

In the wholesale VoIP business model, you act as a “middle man” between the carrier and the end-user. If you are interested in reselling VoIP, you should know you need three main components.

The Softswitch (also called a software switch) is a call-switching node that enables providers to control and signal.

In addition to analytical and reporting tools, it should have VoIP and integrated billing to make it easy to charge clients while transcoding to convert the different protocols and codecs.

LinkedIn is another excellent platform for researching potential clients for your VoIP business, as it has a vast network of companies in different niches and provides a fantastic opportunity to contact them directly without having to go through PR and sales departments.

  • Local Exchange Carriers (LECs) who want to improve their network reach

Your customers can bid farewell to high phone bills and costly equipment and enjoy the ease of communication with their clients and business partners.
