[Asterisk-Users] Aggressive Echo Suppression

Hi everyone,

I have been experimenting with aggressive echo suppression (as defined in
zconfig.h) in order to eliminate the infrequent but still disturbing echo
that we get with our cisco 7940 phones -> asterisk -> PRI   configuration.
Unfortunetely it seems that with the flag on any given call drops after 3
minutes, guaranteed. This happened with both the older production version
cvs 03/18/04 which prior to the changes had an over two month uptime, and
cvs as of last night.

Also just as a matter of interest, anyway to recompile and deploy zaptel /
libpri without restarting asterisk?
