IP Telephony
IP telephony is a fully digital telephone service where voice conversations are routed through an IP based network or through the internet rather than over a traditional copper wire as in the case of analogue services. The digitisation of voice calls brings with it the big advantage of allowing the introduction of value added services like video call capability and integration with PC based software, allowing for a wide variety of interesting business services. SIS has embraced this technology to launch a series of new services that help to improve business communication, and as a result, business performance.
