network, such as Ethernet, in order to operate and provide high quality
communications. This IP network shall be designed according to the
best practice in the market to accommodate high quality Real Time
services over IP. MX-ONE Telephony System provides business class
telephony features. It performs call control, call-signaling, media
transcoding and conversion functions. MX-ONE Telephony System

quality media sessions. The entities of LAN switching and IP routing are

a prerequisite for a functional solution.
