SIP Trunking

Don’t compromise, both voice &
data on one line

With SIP Trunking, you can not only discard the soon to be expiring ISDN line in your office but also enjoy one connection for both voice and data on one line – providing you with not only a fantastic communication solution but also an ability to save up to 50% on line rentals and 25% on calls. Make the move now and take on a ready-made replacement for ISDN today.


The difference between SIP Trunking and VoIP

A SIP trunk can work with your existing PBX (private branch exchange) telephone system which allows you to stick to a dedicated number of phone lines for any individual.  All calls come in via IP and the fact that there’s no extra conversion required means that the sound quality of your calls will be significantly better when compared to VoIP.

With SIP Trunking, there’s no need to change phone numbers, as your existing number can be ported across, so there’s no need to worry about updating your contact details on company documentation.

Never miss a call, even in an emergency

Ever had a blackout or a catastrophic technical failure?  The likelihood is that you have at some point.  The cost of which can be severe for the business but with SIP Trunking’s in-built disaster recovery mechanisms, a disaster doesn’t have to mean it hits you in the pocket.  You can re-route calls anywhere, any time with a virtual phone line that can redirect calls to wherever you need them to.
