[Babar S. <bab...@ya...>]

I updated from latest CVS i think it is fixed that problem a bit,

But now the voice of other end become very low, It is new silence filter ? or I have to enable mic
boost for this ?

When tried from speaker phone i got some wierd noise but its not echo, its like in half duplex
speaker which needs to be muted when speaking with mic.
