Understanding SIP Trunking

As the telecom industry evolves, so does the underlying technology.  One of the most influential technological advances in recent years is SIP Trunking, a term which seemingly confuses even the most tech-savvy people. SIP stands for Session Initiation Protocol, and it is a communication protocol used for signaling and controlling multimedia communication, such as voice and video calls. The most common applications of SIP are in Internet telephony, as well as instant messaging, over Internet Protocol (IP) networks.

But what is SIP Trunking?  It’s essentially a cloud-based service for your phone lines.  Instead of wired landline connections, all of your phones will be connected to an existing PBX and the internet in order to make more reliable call connections.  It’s a voice-over IP, or VoIP, specifically made with businesses in mind.  This means that your internet service is going to cover your internet-capable devices like your business IP phone.  It eliminates the need for multiple phone lines, while still giving a different phone number to each employee who needs it.

You may be wondering why it’s worth switching to SIP Trunking, as opposed to traditional landline phone lines.  On top of unlimited nationwide calling, including Canada and Puerto Rico, you could save up to 40% on your phone bill as compared to a traditional services.  SIP Trunking also opens temporary phone lines when your other lines are busy, so your customers never hear a busy signal.  SIP Trunking allows your phone line to automatically redirect calls in the event of a power outage.  And where customers have an online portal to access whatever you need them to, you can effortlessly transfer calls between locations and/or enable advanced call routing features.  SIP Trunking can save you money, time, and so much more.
