SIP Trunking

Gain added flexibility while reducing your costs

SIP trunking is a type of voice over IP technology, which is delivered over an internet connection. It offers a highly-flexible alternative to ISDN30 and ISDN2, which can achieve a significant reduction in telephony overheads because of the lower line rental and call costs.

High Savings Potential

SIP delivers less costly, more reliable connectivity than ISDN, with savings of up to 75% on line rentals and call costs compared to ISDN. For larger organisations with multiple locations, there is also an opportunity to achieve free internal calls.


No Limits & Highly Scalable

SIP trunking operates in a similar way to a ISDN30 line, but without the limit to the number of simultaneous calls per line. What is more, you can quickly raise or reduce the number of simultaneous calls you can make in line with business requirements.


Fast Access & Prioritisation

SIP trunking is not restricted to any single site, so there is no risk of having to set up new lines in the event of an office move or being forced to change numbers. All you need is an internet connection and you can move anywhere and keep your SIP trunk with the same numbers.


Resilient & Secure

Using our robust data servers we provide a fully-managed trunk with as many channels as you require, with built-in business continuity in case your IP telephone system goes offline. Handle any onsite disruption with ease by rerouting calls to an alternative location quickly and effortlessly.
