We live in a rapidly advancing world, new innovations and technologies are being made to make our lives better in every way. Amongst these many advanced technologies is SIP trunking. It has only recently been introduced and used in the market and up until now it has only proven beneficial to many businesses, as it is similar to a business phone system but only better.

Firstly, you need to understand what SIP trunks really are. In its base level it is almost like a traditional phone line that is wired up to a business telephone network. If you would visit an office today and use its telephone line to make a call, you will not have any idea whether your call is being made on a traditional phone line or an SIP trunk service.

What is SIP Trunking?
SIP stands for Session Initiation Protocol and is the network communications protocol used to control the flow of voice and fax calls using VoIP, and is effectively the method of transmitting the call.

VoIP stands for “Voice over IP”. IP or “Internet Protocol” is the method by which the digitized voice signal is transmitted over computer networks rather than the more traditional PSTN (Public Switch Telephone Network).

To communicate via your IP PBX to outside the enterprise you need a SIP trunk to connect to the traditional PSTN. SIP and VoIP can be considered as your virtual ISDN lines, but with a higher level of reliability and significantly more flexible.

Therefore, SIP services effectively allows organizations to replace traditional, fixed PSTN lines with PSTN connectivity via a SIP trunking solution over the internet. It reduces costs by eliminating the need for local PSTN gateways and costly ISDN infrastructure.

To successfully implement an IP network infrastructure into your organization you need the following components; a PBX with a SIP enabled trunk side, an enterprise device that understands SIP, and a fast and reliable internet connection.

Why do I need SIP Trunking?
SIP trunking services are simpler and easier to configure and are far less expensive to design, operate, manage and upgrade. Therefore, any investment with a SIP provider is quick to give an ROI.

SIP lines deliver cheaper national and international calls, high quality voice and a single, unified infrastructure. This is why SIP is hot stuff in the world of unified communications.

SIP trunks can add value and enhance the features of any telephone system including old legacy systems. They adapt quickly, control costs and offer features not available from standard telephone line service.

Deploying SIP is the next logical step in the advancement of business communications, as you are able to benefit from a single, IP based infrastructure rather than inflexible, soon to be redundant, traditional telephone networks.
By combining voice, fax and data into one network you are simplifying your communications and management, running costs are reduced and it has also been proven that businesses can save up to 60% on their telephone bills.
These benefits are great but they are pointless if correct installation is not done.

You need to make sure that you or your SIP trunking system service provider have made correct calculations as to how much bandwidth will be available to allow the required number of constant calls to be made and or received. Another part of the installation process you need to make sure of is that whether all the correct hardware and software has been supplied, installed and configured by your SIP trunking service provider.
