Summary: [patch] It's necessary to have high pass filter for
tx signal of DAHDI.
Description:
It's necessary to have low frequency filter for tx signal of DAHDI.
Otherwise, low-frequency signal from IP can reach a leased line, and
return back with nonlinear distortions. This will break an echo canceller.
