Re: [Linphone-developers] DTX / VAD for Speex in linphone

[Johan Pascal]

Hi,

speex codec directly manages the VAD/DTX as long as you use vbr=on or 
vbr=vad in your fmtp parameter, can you check these parameter is 
correctly set in the SDP INVITE and peer response to the invite ? During 
silence you shall have fewer and smaller packets.

By the way, speex is now superseded by opus, why do you need to use speex?

regards,

johan
