3.1.1. Voice over IP
VoIP is a technology to transmit voice traffic, such as voice telephone or fax, to IP network. By
using Digital Signal Processor (DSP) integrated in VoIP equipment, a voice signal can be
segmented by frame units and send to other devices connected to each other. DSP of other
devices combines the voice packets each other and delivers the voice signal. The voice packets
transmit to each other as to comply with H.323 of ITU-T standard.
Voice application is different from data application as it is responses more sensitively to delay.
Therefore, when VoIP application is used, the network configuration needs to be well adjusted,
so voice application can be used smoothly from VoIP equipment. These adjustments include
Protocol Tuning to improve QoS, consideration of Traffic Shaping, adjustment of MTU Size.
All the commands being used for VoiceFinder Gateway can be accessed to console, telnet or
web-client.
Voice over IP is a function basically processed from the software. Voice port of the gateway
supports a specific signaling type to process voice.
