b100p echo problems

Hello,
I have a b100p installed on intel motherboard and atom processor,

Freepbx with asterisk 11 and dahdi 2.6.2 patched for the b100p

all is going well but, from and to some specific number, all italian number i receive a terrible echo,

i tried to modify tx and rx gain, but without solution, these specific calls are very noisy,

activated echo cancellation, echo training, but anything change.

calling the same numbers from the same line with old analogic pbx don't create noise or echo..

any help?

thanks
Francesco

HI
Download this driver and install directly :
downloads.openvox.cn/pub/drivers/dahdi-l...e-2.6.2+2.6.2.tar.gz

Do not need to do any patch.

hi,
i tried 2.6.2, 2.6.0, 2.5.0. 2.9.0. all have the same problem,

if i phone via SIP from same phone to same phone number i don't have echo, if I use DAHDI I have echo,

tomorrow i try again to install 2.6.2

HI,
