“Extension” - is the extension of the telephone line (PBX) or the Centrex system. It works as an association and allows calling to certain telephone sets without the necessity of dialing the telephone number, but only by dialing a short combination of digits, reaching the desired subscriber.
What we do best - World-Link provides local, national and international long-distance calling and also broadband access to its switches at vastly reduced rates, allowing our customers to realise huge savings when making calls.
