SIP trunking (Session Initiated Protocol) can turn your average office telephone system into a powerful internet telephony service – or VoIP (Voice over Internet Protocol) there by reducing telephony downtime.

Instead of communicating via traditional ISDN lines, a SIP enabled VoIP telephone system allows people to talk over the internet by exchanging digital signals instead of analogue ones. SIP trunks allow you to increase your call capacity without compromising on quality and placing calls over a data network allows your phone system to expand and become virtually limitless.

How can SIP and VoIP enhance communications and reduce telephony downtime?


The internet can offer very fast connections and transfer of signals which give us much more than slower, legacy telephone boxes.


Many organisations that have implemented SIP claim to have found cost reductions of 50% on line rentals and 25% on call costs.

Together, SIP and VoIP can allow your business to produce ROI within six months by:

  • Eliminating the need to invest in costly and less capable equipment and hardware
  • Using only one connection for data and voice
  • Reducing expenses; employees are less inclined to travel as voice and video quality is improved
  • Accommodating up to 100,000 users without extra, time consuming and costly installations
  • Bridging gaps between countries, locations and people, allowing for home or remote workers – your phone system is accessible wherever there is an internet connection
  • Increasing productivity, output and saving on employee time by communicating faster and more clearly than ever before

Quality of Service

If companies are looking for the highest SIP and VoIP quality it is important to establish Quality of Service (QoS) agreements with your connectivity provider. For example, although SIP and VoIP can work effectively over the public internet, it works much better when placed on a QoS network such as MPLS. By using a solution like MPLS, you can add certain priorities to your data or voice traffic which can further help eliminate delays and allow for proper scaling.

The industry is already seeing a decline in the number of ISDN installations due to a growing interest in SIP and VoIP. As modern businesses continue to increase its use of data services like email, internet and applications, the need for SIP and VoIP communications will continue to rise alongside. It is thought that by 2025 there will be no need for traditional ISDN lines as we know it.

The ability to reduce costs and effectively do more with less – and for less – is something that not many businesses during times of economic disparity can afford to miss out on. SIP is entirely future proof, as you can scale up or down, and add features as and when you need to with little disruption or extra cost to your business.
