Services: Carrier Network Services

Although the main UK incumbent telecoms operator is still BT, with the emergence of so many new telecoms operators and an array of confusing services and tariffs to choose from, it is not always easy for companies to make the right choice when selecting a carrier network over which to send their telephone calls or establish data and Internet connections.

Cityfringe have many years experience in dealing with these issues and can advise and reccomend the most suitable combination of packages to suit the needs of your organisation whether a small charity or a global corporation. We can conduct audits and reviews of your existing telecoms infrastructure to ensure you are not paying for services you are no longer using, and arrange for the supply and installation of additional lines and services where required.

Although BT are the UK's main service provider of last mile connectivity (from the exchange to the customer premises) there are a number of other options available to high spending customers requiring direct connectivity to alternative network operators like COLT, Cable & Wireless and MCI, to name but a few. In such cases, Cityfringe are well versed in the intricacies and complexities of achieving such connectivity and can advise on all aspects of the following services.

    • Simple standard Analogue lines (just like at home)
