freetdm.conf is mandatory, zt.conf is optional. The gain parameters
specified in freetdm.conf are common to all board manufacturers, the gains
are applied *after* reading from the driver and *before* writing to the
driver, so if you changed the gains in freetdm.conf, is no surprise DAHDI
debug logs did not indicate any gain change. The DAHDI drivers have their
own kernel-level gain adjustment. You will have problems if you're tweaking
gains at both the kernel level and the freetdm level (user space).

Post your freetdm.conf, freetdm.conf.xml, zt.conf, system.conf files using
http://wiki.freeswitch.org/wiki/Reporting_Bugs#Using_The_Pastebin

Note you can tweak the gain live during the call using the fs_cli command
'ftdm gains'
