As global businesses continue to explore the many communications options at their disposal, they are increasingly turning away from legacy telecom systems in favor of more advanced alternatives.  One such option – and one of the fastest-growing business communications systems today – is Session Initiation Protocol (SIP).


The technology is attractive for both its functionality and financial benefits, which spurred a three-fold increase in SIP usage from 8.5 million SIP trunks in 2009 to 24.3 million trunks in 2013. SIP is quickly becoming a part of many businesses’ common vernacular. However, for those who have yet to explore the platform, let’s go back to the basics of this technology.


SIP: The Basics


SIP is a popular communications protocol used to create real-time sessions for users over the Internet or network. This technology can be used to:


  • Facilitate real-time media connections such as teleconferencing, video conferencing, and instant messaging
  • Support multi-media sessions and large amounts of data
  • Help enable internet telephony Voice Over IP (VoIP)


What Are the Benefits of SIP?


  • Cost Savings – Using SIP can save businesses money in a variety of ways. Because implementing the system does not require any complicated software or hardware, setup is relatively easy and inexpensive. Additionally, with SIP, businesses no longer require Public Switched Telephone Network (PSTN) gateways, bringing communications costs down even further.
  • Consolidation – With SIP, businesses can merge all communications into one single system. Companies are constantly looking for simpler ways to do business; converging local, long distance and broadband Internet services helps accomplishes that goal.
  • Everything Local – SIP is particularly beneficial for global organizations that utilize an international phone service for a large volume of calls. The calls travel as IP signals and are not tied to land-based phone lines, allowing businesses to set up a local presence in multiple countries, no matter where in the world they are physically located.


The potential advantages of SIP stretch far beyond the benefits listed above, including: reducing redundancy, maximization of bandwidth, and scalability. Industry analysts may vary on their exact projections for SIP usage, but one thing they can all agree on is that its continued growth is a near certainty.
