[Freeswitch-users] FIXED: Re: 4.0.5 Linux Kernel, GCC 5.1.1, ftmod_zt and DAHDI 2.10.1 (Fedora 22) failing to work in previously working setup

Mon Jun 29 14:06:12 MSD 2015

For those who may be seeing similar, I do not yet know what changed
between Fedora 20 and Fedora 22 (Fedora 21 had some strangeness to it
with FreeSWITCH that I never had time to figure out) which caused
dahdi_echocan_oslec module to not be loaded automatically. I have not
yet figured out why this was. The compilation bugs and installation bugs
have been or are being fixed. I have a working system, except now the
echo cancellation which was a bit slack is now over zealous.

Thank you,
Trever
