84-12-17 Jitter Buffer Mode
If the jitter buffer is set to adaptive, the buffer is adjusted
(larger/smaller), depending upon network conditions.
If the jitter buffer is set to static, it will never adjust and al-
ways have the same size buffer.
84-12-18 Voice Activity Detection Threshold
This program is used to set the threshold of the db level
that the system uses to determine silence. If VAD is ena-
bled and this threshold is reached, the system will stop
transmitting "silence packets" across the network.
84-12-33 G.722 Audio Frame Size
Assign the G.722 Audio Frame Size
The smaller the packet sizes the more bandwidth that is
consumed. However when a smaller packet is lost in a
network a smaller amount of the voice is lost with it.
84-12-35 G.722 Minimum Jitter Buffer size
This program assigns the minimum size that the jitter buf-
fer will use.
84-12-36 G.722 Average Jitter Buffer size
This program assigns the average size that the jitter buf-
fer will use.
84-12-37 G.722 Maximum Jitter Buffer size
This program assigns the maximum size that the jitter
buffer will use.
84-12-38 RTP Filter
This program is used to avoid audio path problems in
times of heavy RTP traffic.
When enabled, the system will check the sender's IP ad-
dress that is sending RTP packets. If it does not match
with the IP address of the actual caller, the system will ig-
nore it.
84-34-01 VoIPDB Setup DTMF Relay Mode (02-Networking)
Select DTMF Relay Mode.
84-34-02 This program assigns the way the system handles DTMF
across the SL Net network. For profile 1, Type 2 (Net-
working) this value should match in all SL Net systems.
4.3 Call Routing - Outbound
Program
Number
11-01-01 System Numbering
This program is used to assign the Trunk Access code (9
by default) and the special trunk access code (unas-
signed at default).
The trunk access code used to make alternate calls must
be set to a type 4 (special trunk access code).
