VoIP is a service in which voice data is transmitted over the Internet just like normal data traffic on the Internet. VoIP is also known as Internet telephony or IP telephony. When the Internet connection is broadband, VoIP is usually referred to as broadband telephony.
Regardless of the terminology used, VoIP phone service is a method of providing voice communication using the infrastructure of the Internet. You can browse this site to consider the best VoIP services for your organization.
VoIP telephony services use the existing Internet infrastructure, which is already installed, and the voice signal that is converted into digital audio is sent in packets. VoIP services can be connected to the public telephone network (PSTN) and calls can be made to other computers, VoIP cell phones, or regular telephones.

The services provided by VoIP are similar to those provided by PSTN with options for call forwarding, call waiting, caller ID, auto redial, and conference calling. VoIP has a security advantage over conventional telephones – audio content is broken up into many parts over a very short duration and sent as packets over the Internet. There is no need to receive packets sequentially at an intermediate point. It is very difficult for anyone to intercept VoIP calls.
VoIP has become very popular in recent years as it has become an inexpensive voice communication solution with wide user acceptance and a large user base. Service providers do not have to bear the cost of installing infrastructure in the form of cables and switchgear, because the Internet infrastructure is already available.
The PSTN service provided is required to digitize voice and transmit data after it is converted into a digital signal. The Internet infrastructure already carries this type of signal, which significantly reduces costs for service providers. As a result, VoIP telephony services are offered to customers at much lower rates compared to PSTN.
