[asterisk-users] Echo cancellation in a sip channel

[Alexandre Rodrigues]

Hello all,

I have a Linksys spa3102 with one FXS and one FXO port.

The problem is that I have a lot of echo when using the fxo port, the sound
is of very low quality.
 So, since I am  passing from a FXO port to a SIP channel I ask:

             is there any Sip echo canceler software for asterisk??

Thanks in advance.

Alex
