If your 3CX system has suddenly stopped working over Sky Broadband, it’s likely due to the automatic blocking of the 3cx.co.uk domain by Sky’s Broadband Shield. Fortunately, there’s a straightforward fix, read on for a step-by-step guide to get your service back up and running.
3CX and Sky Broadband Blocking
Over the past weekend, Sky Broadband users began experiencing issues connecting to 3CX. The root of the problem? Sky has reportedly added 3cx.co.uk to their Broadband Shield’s list of blocked sites.

This sudden restriction affects many small businesses and remote workers who depend on reliable VoIP phone systems like 3CX to stay productive.
