Configure Dejitter Buffer (Advanced) - Patton electronics SmartNode Series Software Configuration Manual

SmartWare Software Configuration Guide
This procedure describes how to configure voice volume.
Mode: Profile VoIP
Step
1 node (pf-voip)[ name ]#voice-volume value
2 node (pf-voip)[ name ]#exit
3 node (cfg)#context cs
4 node (ctx-cs)[switch]#interface isoip name
or
node (ctx-cs)[switch]#interface h323 name
5 node ( if-type )[ if-name ]#voice-volume value
Example: Configure voice volume
The following example shows how to set the voice volume for the VoIP profile to 10 dB and specify an other
value 20 dB for a specific H.323 interface
SN>enable
SN#configure
SN(cfg)#profile voip ISoIPProfile
SN(pf-voip)[ISoIPPr~]#voice-volume 10
SN(pf-voip)[ISoIPPr~]#exit
SN(cfg)#context cs
SN(ctx-cs)[switch]#interface h323 IpBackbone
SN(if-h323)[IpBackb~]#voice-volume 20
Configure dejitter buffer (advanced)
Packet networks always introduce a certain amount of jitter in the arrival of voice packets. To compensate for
the fluctuating network conditions, SmartWare has implemented a dejitter buffer in its voice gateway. Typical
voice sources generate voice packets at a constant rate. The matching voice decompression algorithm also
expects incoming voice packets to arrive at a constant rate. However, the packet-by-packet delay inflicted by
the network may be different for each packet. The result: packets that are sent in equal spacing from the left
gateway arrive with irregular spacing at the right hand gateway, as shown in
VoIP profile configuration task list
Command
30 • VoIP profile configuration
Purpose
Set the voice volume to value in dB
Optional:
Change to CS interface configuration mode
to overwrite the settings in the VoIP profile in
a specific CS interface
Set the voice volume to a different value as
specified in the VoIP profile
