SIP (Session Initiation Protocol) Trunking is a method used to deliver real-time voice communication over VoIP (Voice-over IP).

Instead of using traditional ISDN and PSTN services, SIP calls can be transmitted between data networks and connected directly to the Public Telephone Network.

SIP trunks are quickly growing in popularity and becoming the common way for businesses to manage voice communications. If you are considering adopting this technology for your organisation, here are some benefits you could gain from VoIP and SIP trunking services:


One of the most well-known benefits of switching to SIP trunks is the cost savings. IP connections are cheaper than ISDN lines and the pricing is based on a per-user basis rather than varying charges for different types of calls. Because long distance and international calls can be easily connected through the internet, they are considered as local calls which means that it is significantly cheaper.


Rather than paying for voice communications and data separately, SIP trunking means they can be moved onto one single network which will save you money whilst offering a reliable service; this is especially noticeable when you have multi-site locations. Regardless of the size of your business, the infrastructure will always be in place if you experience growth and you will be able to manage both voice and data operations efficiently.


SIP trunks have the capability of expanding as your business grows as they are easy to adjust and extremely flexible. Whether you are hiring more remote workers or opening new sites across the world, you have the ability to keep the same existing telephone number structure wherever you move to.


By switching to SIP trunking, you can bring together cloud-based applications through unified communications; this way, both real-time and non-real-time communication can all be dealt with on one platform. These applications include, but are not limited to, video conferencing, instant messaging, collaboration apps and mobility.


The streamlined communications you can achieve with SIP trunks gives you the ability to connect to mobile devices and allows your remote workers to remain connected to your on-premise communication system. This means you can achieve ultimate accessibility and increase productivity wherever your employees are based.


SIP trunks provide a lot more reliability than traditional telephony services and can be implemented into your business’ disaster recovery plan. If disaster ever strikes and your system is compromised, you have the ability to reroute your services to another location, mobile devices or wherever you desire so your business operations are not at risk.

No matter what size your business, by utilising VoIP and SIP trunking, you can enhance your business communications and manage them more efficiently. If you are interested in the benefits that SIP trunks can bring to your organisation, contact us today to find out what we can do for you.
