Some people seem to think that SIP and VoIP are competing technologies. Is this true?

VoIP Defined

VoIP as an acronym stands for Voice Over Internet Protocol. It is a general term that covers any phone calls made over the Internet, Other terms that are used instead of VoIP include, IP telephony, Internet telephony, voice over broadband, broadband telephony, IP communications, and broadband phone service. Fundamentally they all describe how the Internet is employed to digitally transmit the voice signal to another telephone or endpoint.

As VoIp is limited to voice transmissions, it helps keep usage to a minimum. Your VoIP provider may even offer you a much larger amount of unlimited minutes for you to get a better deal. So when it comes to Voice transmissions, VoIP is hard to beat when it comes to flexibility and price

The meaning of Protocol

A protocol is simply a set of digital rules for message exchanges within or between computers, phones or other digital devices. We could get into the detail of syntax and semantics but to keep it simple these protocols have been developed into industry standards, making it simple for multiple suppliers to build endpoints that can talk to each other.

Understanding SIP

Session Initiation Protocol (SIP) is a communications protocol ie a set of digital rules that is generally employed to manage multimedia communications for example, voice and video calls.  SIP, therefore, it is important to note, is one of the unique protocols that enable VoIP.  

SIP can be used to send information between just two endpoints or many.  As well as voice, SIP can be used for video conferencing, instant messaging, media distribution and many other applications.

At the most basic level if you want to an umbrella solution to your business communication needs, SIP trunking it is your best bet. Adding further tools, such as Asterisk, will make your SIP platform perform even better because you have the opportunity to customize it to your needs.

 SIP technology is today fast becoming the norm method for deploying VoIP. Some of the benefits of using SIP to enable your VoIP is the reduced costs, the added efficiency, as well as its increased scalability compared to older systems.


SIP vs. VoIP therefore are not competing technologies. SIP is an industry standard method of achieving VoIP and it’s the preferred deployment method because of its scalability.
