Learn what SIP is and it’s telecommunication benefits

What is SIP?

SIP stands for session initiation protocol and it is simply an accented version of the IP language by which IP devices communicate on our VoIP 2.0 platform. You can think of IP as the English language where SIP could be described as a certain dialect.

It would be impossible to suggest an example as SIP delivers a brilliant audio which must be heard first hand in order to know what I mean. The clarity of the voice quality comes delivered with an exciting surprise as most don’t expect the full spectrum, high definition sound they experience.

Thankfully, I can tell you that the appreciation has still not worn off in my case. Just about every time I use my SIP phone I still feel the excitement and speakerphone conversations are unbelievable. I expect this lingering love for SIP is still in the air due to the enormous amount of time I have spent living my life without it.

What is a SIP Trunk?

A SIP Trunk is a virtual, VoIP phone line that utilizes a Broadband connection for access, and offers up to 40% savings over traditional telephone lines.

Why would I choose SIP Trunking over Analog (land lines)?

The main difference between Analog lines and SIP Trunks is the flexibility. Analog lines are basically the line you get from a phone company, with limited functionality and high costs. SIP Trunks, however are quality reliable, less expensive, and offer network solutions. Today, with SIP, our technology choices are much more dynamic and offer a host of solutions and features tailored for each individual company.

SIP Technology (technical)

SIP allows two devices to have several different methods of one, or many, different kinds of media/communications streams running. It is currently most widely applied in VoIP, or, voice over IP. In this way, it allows residences or businesses to transmit several voice paths over one channel. This can allow for personal phone numbers for everyone, but only one phone line.

This protocol is an open source application layer signaling protocol that allows people to communicate with others using different devices. SIP has made it’s way to the top of VoIP communications because of it’s long history with IP, or, the internet protocol, rather than coming to us from the telecommunications world. SIP is a fan of running on UDP, TCP or SCTP.
