RTP
DSP– use this section for transferred data optimisation. When enabled, packets
are not sent uselessly when the user does not speak. VAD stands for Voice
Activity Detector.
VAD off
VAD according to G.729 Annex B
VAD light
Generate comfort–noise – use this parameter to generate some noise into the
call. Since analog line users are used to some background noise, similar noise is
simulated here for comfort.
Mask lost packets – use this option to activate lost packet masking
optimisation.
QoS
The TOS/DiffServ section helps you set the outgoing packet parameters in order to
define priority in processing by network elements.
SIP – hexadecimal value of SIP packet priority.
RTP – hexadecimal value of RTP packet priority.
Default values – reset the default values for the two parameters. The default
values are optimised for voice transmission.
