SIP Trunks

Whether you’ve got one sip phone, a hosted or in office PBX system, a SIP trunk can save you money on your phone calls. They provide greater flexibility, improved connectivity and usually lower costs for communications.

What are SIP Trunks?

If you’ve got a telephone or a PBX on the wall in your office, both of these are likely connected to some kind of phone line, whether it’s an ISDN line or traditional copper phone line. Your PBX may be connected to multiple lines, one for each phone or number you have.

You can think of SIP trunks and Voice over IP (VoIP) technologies as synonymous. A SIP trunk lets you connect your SIP phone or internet connected PBX to an internet based ‘VoIP’ phone line. This runs over your internet connection, so you shed many of the limitations of traditional phone lines. For example, you can run multiple calls simultaneously over a single internet connection. The only real limit is the amount of bandwidth you have. Bandwidth refers to the amount of data you can send across your internet connection at any given moment in time. A good metaphor is to imagine cars in a tunnel. The tunnel is your internet connection. The cars represent data you’d like to send and receive over the internet. The bigger the tunnel, the more cars, or data you can pass through it.
