An Analogue line is a single copper cable that is run in to a building by your carrier line provider. Before ADSL was available Analogue lines were used for both voice and data. Now these lines are used mainly just for voice calls as the total bandwidth available is only 56k. Fax machines, alarm systems, elevators, etc, still use analog lines.
Long distance and international service are provided by both VoIP providers and traditional phone companies. Traditional phone companies depend on a system called the PSTN to transmit calls. The PSTN has been in place for as long as there have been phone calls. It is the original method for sending a call and is quite antiquated. Still have a PSTN? We can help migrate to VoIP which will be much less expensive for your firm.
