RTP Configuration
The second configuration section for Triton VoIP is RTP Configuration,
with the following settings:
Parameter Description
Codec By default, G.711 (provides toll quality digital voice
encoding), G.723/G.729 (uses low rate audio
encoding to provide near toll quality performance
under clean channel conditions) and G.723.1 codecs
are automatically enabled. These option are not
configurable. On the 30-port board, G.723.1 cannot
be selected; on the 12-port board, G.723.1 cannot be
deselected.
Note: AltiWare always uses the same code on both
transmit and receive directions. If a third
party H.323 device is used which supports
both G.732.1 and G.729, this device’s
preferred codec setting must be configured to
use the same as AltiServ’s.
G.711/G.723/G.729
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.
Select G.729A without Silence Suppression or
G.729AB with Silence Suppression.
Note: If G.729AB with Silence Suppression or
G.711/G.723 with Silence Suppression is
selected, the bandwidth needed will be
decreased, but the voice quality may degrade
slightly.
