<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US"><span> </span>I
have questions about VAD and echo cancellation. My FS is Version 1.0.head
(git-) under Windows XP. My soft-phone is X-Lite. I use earphones and microphones
for sip 1 which means the talking and hearing are separated; on the other hand,
I use NB for sip 2 which makes the talking and hearing in the same place. Sip 1
(1000) calls sip 2 (1001) via FS. When I say something via sip 1, the echo will
occur, and the echo will only occur on sip 1.</span></p>
<p class="MsoNormal"><span lang="EN-US"><span> </span>How
do I cancel the echo? Buy a hardware card or something else? I have two
gateways which are Wellgate2644 and ata171m. Please give me some suggestions.</span></p>
<p class="MsoNormal"><span lang="EN-US"><span> </span>When
I enabled VAD, I found something strange. In the start of the session, I can
hear the noise and echo on sip 1. If I say something via sip 2, the echo and
the noise will disappear. Then the echo will not occur on sip 1 only in a short
time, about several seconds. The echo and the noise will occur gradually if I
say something via sip1. Is it a normal situation?</span></p>
