Hi, folks:
Yesterday I added a second TDM400P card to a working, echo-free server
running HPEC.
Today, I'm getting these messages:
Apr 20 09:12:12 WARNING[5679]: chan_zap.c:1551 zt_enable_ec: Unable to
enable echo cancellation on channel 3
along with complaints of severe echo. The channels have all been tuned
using 'fxotune -s' and the echo numbers are all under 2%. I guess that
Asterisk can't do echo cancellation on these channels.
Why would I be getting this?
Maybe I would be getting this because I didn't have the zaphpec_enable
in my system startup :)
So -- for future reference, in case anybody else makes this mistake:
zaphpec_enable has to run at boot time, after the zap modules are loaded.
I'll go back to my corner now.
