Ask Us Anything

Voice over Internet Protocol, also called IP telephony, is a method for delivering voice communications and multimedia sessions over Internet Protocol networks, such as the Internet. Basically, it sends your phone calls through your internet connection rather than copper phone lines.

If you have DDI numbers that you wish to keep, we can transfer your existing numbers to VoIP. They are then with you for life and can be used from any office and any location.  For example, you can have London numbers piped to your office in Eastbourne, and there is no charge!

We bill all services and calls on a monthly basis. Calls are fully itemised and charged on a per-second basis for the previous month.

Every business has different requirements and we aim to cater to the needs of our customers. It is also dependant on which service you are taking out but typically we can offer contracts from 30 days to 5 years.

We provide solutions for businesses of all sizes, ranging from individuals through to multi-site corporate clients. Regardless of the size of your business, we have the knowledge to help your communications work better for you.
