The primary configuration for the Triton VoIP is the H.323 Configuration,
with the following settings.
• G.711 Enable—provides toll quality digital voice encoding and is
not configurable—that is, you cannot de-select it. It guarantees
interoperability when other voice compression (e.g. G.723.1) is not
available or when better voice quality is desired.
• G.723.1 Enable—uses low rate audio encoding to provide near toll
quality performance under clean channel conditions.
• Silence Suppression—suppresses silence packets during VoIP
sessions. When silence is detected during a call, AltiWare IP stops
sending packets to the other side. When silence is detected during
voice mail, the silence period is not recorded.
AltiWare IP disconnects the voice mail session when a silence
period exceeds 7 seconds during voice mail recording over VoIP.
• Jitter Buffer (msec.)—indicates the delay, in milliseconds, used to
buffer voice packets received from the IP network. Voice packets
sent over the IP network may incur different delays due to network
load or congestion. The Jitter Buffer helps to smooth out the delay
variation in the arriving voice packets and maintain voice quality at
the receiving end. The default setting is 30 milliseconds.
