What Is SIP and How Does It Apply to Your Office Telephone System?

Session Initiation Protocol (SIP) is a communications protocol for controlling voice and video communication sessions (calls) over an IP based network. It contains instructions for processing the the call, identifying its origin, destination, components, and status. 


SIP is used in Internet telephony, video conferencing, and to send SMS messages. The popular VoIP (Voice Over IP network) phone calling services may use SIP (or other communication protocols). However unlike VoIP, SIP is not limited to voice and can also carry video and data. 


Another important distinction is that a physical SIP phones can function completely independently of a computer, making them ideal for business environment.  A SIP phone only needs a good broadband connection.


Sip phones can be either an actual phones or a software solution (a softphone). An actual SIP phone does not look any different than a regular phone, but is designed to handle calls over the Internet connection instead of a traditional phone lines. It can have both an Internet port (accepting a Ethernet cable) and a standard phone port, or just an Internet port.  A softphone allows a personal computer or mobile device to emulate the functionality of a SIP phone.
