The legacy phone network, the Public Switched Telephone Network (PSTN), is slowly being phased out. The old way of placing calls, using traditional Analogue and PRI lines in your business is gradually being replaced with new-age internet technology.
Voice over IP (known as VoIP) offers many advantages over traditional PSTN lines. Among these is better flexibility, superior audio quality, lower operational and variable calling costs, and the ability to scale without adding more equipment. Best of all, it doesn’t matter what phone system a business has, there is a high possibility that their existing PBX can still work with VoIP lines.
