Carrier Grade VoIP SIP Trunking

Let's start with what SIP Trunking is not. It is not a whole bunch of copper lines from big telephone companies, used only sparingly but costing you a heap in line rental fees. SIP Trunking is a business-grade voice solution that uses the internet instead of traditional fixed Public Switched Telephone Network (PSTN) lines to connect to your telephone carrier.

SIP Trunking delivers many benefits:

  • Eliminates those rental costs on unused copper lines and costly BRI's (Basic Rate Interfaces) and PRI's (Primary Rate Interfaces) or ISDN's.
  • No need to invest in expensive PSTN gateways and additional line cards as you grow.
  • Last (and probably first for most users) - the cost per call is less than conventional call charges and the quality is vastly superior.

How Does it Work?

SIP (Session Initiation Protocol) is a standard protocol for telephony over the internet. It is often referred to as
VoIP (Voice over Internet Protocol). however our SIP service is designed for businesses wanting
Carrier Grade quality and not just domestic.

Unlike in traditional telephony, where bundles of physical wires/fibre are required, a SIP trunk allows a business to replace these traditional fixed lines with PSTN connectivity via a SIP trunk using a Broadband Internet Service.

SIP trunks give significant cost-savings for businesses, eliminating the need for local PSTN services.

What You Need

There are three components necessary to successfully deploy SIP trunks: a phone system with a SIP-enabled capability, a modem/router and an internet connection (preferably one dedicated to your phone services).
