<P><FONT SIZE=2 FACE="Arial">Hi everyone,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">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.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Also just as a matter of interest, anyway to recompile and deploy zaptel / libpri without restarting asterisk?</FONT>
