[asterisk-users] The High Performance Echo Canceller (HPEC)

[Boris Bakchiev]

Hi,

Has anyone noticed degraded voice quality with HPEC?
I have a client running TE4XX card who configured HPEC for couple of
channels with echocancel=1024.

Whenever HPEC is used you get a background static in voice.
When HPEC is not used everything is crystal clear.

What could cause this static?

regards
