Traditional Phone Lines

Business telephone or analogue lines have been around for nearly 100 years. These traditional lines can be used for a simple, good-value phone line or use with – broadband, PDX, fax or alarm.

We offer competitive business analogue line deals to suit your needs; all of our lines are supported by Openreach, meaning you experience the highest quality of service, with minimal interruptions. Because we use the BT Openreach infrastructure switching your current line to us is a simple process and because we are a wholesaler, we can pass on significant savings to you for calls and rental.


ISDN2 & ISDN30 Phone Lines

ISDN (Integrated Service Digital Network) transmits voice and data signals concurrently over copper or digital lines via exchanges. Like traditional phone lines, ISDN has been around for many years and it is a proven technology strengthening the reliability when it comes to the quality of voice calls.

ISDN is still a present solution to we offer but most businesses are now moving towards VoIP & Hosted Voice solutions due to a number of reasons, particularly being the ISDN Phase Out which is happening in 2025. ISDN still has a place until then, however, you will not be able to purchase any additional lines in 2020. So now is a perfect time to review your telephony solution and speak us to find the best solution for your business.

Are you ready for the ISDN switch off?
