182 AltiWare OE System Installation & Administration Manual
The primary configuration for the Triton VoIP is the H.323Configuration,
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 4-port and 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 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.
The Jitter Buffer should be adjusted according to the
WAN bandwidth allocated to data traffic.
