7-14 AltiWare OE System Installation & Administration Manual
The primary configuration for the Triton VoIP is the H.323 Configuration,
with the following settings:
Parameter Description
G.711 Enable Provides toll quality digital voice encoding and is not
configurable—that is, you cannot deselect 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.
This option is also not configurable. On the 30-port
board, it cannot be selected; on the 12-port board, it
cannot be deselected.
FastStart Enable Fast connect feature allowing endpoints to establish
channels without waiting for an H.245 connection to
be opened.
MWI Enable Message Waiting Indication (MWI) feature which
activates a message waiting light on an IP phone to
inform a user of unheard voicemail messages.
Silence Suppression Suppresses silence packets during VoIP sessions.
When silence is detected during a call, AltiWare
stops sending packets to the other side. When silence
is detected during voice mail, the silence period is
not recorded.
AltiWare disconnects the voice mail session when a
silence period exceeds 7 seconds during voice mail
recording over VoIP.
G711 Jitter Buffer
Range (ms) Indicates the delay, in milliseconds, used to buffer
G.711 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 initial values
for the jitter buffer is 10 min. to 20 max milliseconds.
The jitter buffer should be adjusted according to the
WAN bandwidth allocated to data traffic.
