The Key benefits

Why choose a SIP Trunking service for your business? 9 key reasons to switch to the VOIP system today.
  • No more line rental, ever For too long, businesses like yours have had to pay through the nose for the simple necessity of having phone lines. It's time to say no more, and never pay line rental again. And the benefits of SIP Trunking does not end there.
  • Use your existing PBX Love your current PBX? One of the key benefits of SIP trunking is its ability to work with all IP PBX. So you do not need to spend time training your staff or spend money replacing. Just pure savings spot on.
  • Rapid ROI SIP Trunking does not require a significant capital expenditure but immediately begins to reduce costs while also maintaining the features customers have with their local PBX.
  • Reduced call cost This is a no-brainer for you, but your customers might not be aware that SIP trunking can dramatically reduce the cost of making and taking calls.
  • Business continuity Initiate disaster recovery capabilities through redundant Enterprise trunks.
  • Unified Communications SIP Trunking provides a gateway to creating an IP-based UC system that brings together voice, data, Instant Messaging, presence, and application sharing.
  • Reliability SIP Trunking is very stable. Rather than being at the mercy of local events such as power or circuit outages, SIP trunking can automatically be rerouted to other offices, mobile phones, or virtually anywhere based on your business rules.
  • Mobility SIP Trunking can help tie together mobile devices and remote workers by enabling a blend of premise and cloud based services.
  • Flexibility The perfect solution for businesses that are starting up, moving office, growing or in fixed-term leases; our SIP trunks enable seamless routing of geographic and non-geographic numbers, to any location. This allows your customers to move office and keep their same geographic number without incurring any ongoing call-forwarding costs or costs associated with producing new company stationery, adverts or directory listings.

More Phone Lines Fast


SIP (Session Initiation Protocol) is a technology that allows you to make calls over an IP connection, rather than a traditional phone network. This reduces costs and helps businesses maximise their network investment. If you have invested in fast internet access like fibre, SIP can help that investment go further.

You'll get more flexibility than with a traditional phone service, you can take your number with you if you move, or market your business locally around the country.


More and more companies are considering a switch to some form of SIP voice. The reasons for this are the obvious cost savings combined with the greater flexibility. In short, enabling businesses to do more for less.

You can also take advantage of more cost-effective and comprehensive disaster recovery options to help protect your business.

Savings Saves up to 50% on line rentals and 25% on calls. Expensive.
Flexibility You’re in control. Add lines, Take them away, split calls - it’s up to you. Sorry, can’t do flexible.
Control Choose how and where you want calls delivered. Make changes instantly. Changes take months. At the mercy of suppliers.
Future Well mapped out and ready for voice/data convergence. Going nowhere fast.
Contingency Handles emergencies with ease. Reroute calls to backup sites in seconds. Hope nothing bad happens.
