[SIPForum-discussion] Silence suppression attribute based on rfc3108

[anuradha.kumar1 at wipro.com]

Hello Manpreet,

 

I had a chance to look at this. VAD or silence suppression is used to
save bandwidth in a case where the originating and terminating parties
do not speak but still the background voice gets played which is
unnecessary. 

 

Now coming to your question whenever not indicated silence suppression
or Voice Activity Detection is set to ON. I guess we can verify this as
well by monitoring it by network analyzers like wire shark. Please refer

Hi

 

If the silence suppression attribute is not present in SDP, whats the
default behaviour? Would the absence mean ON or OFF for a certain media
type?

 

thnx
