i've got calls coming into an 11.21.0 box. The internal phones are

Using an analogue internal phone, the remote party always hears an echo
on it's side. We do not hear an echo. Doesn't matter who is the calling
party.
But if we use a SIP extension, no echo.
I've built /lib/modules/4.3.3-303.fc23.x86_64/dahdi/dahdi_echocan_oslec.ko
And requested oslec echo cancel:
grep oslec /etc/dahdi/system.conf
echocanceller=oslec,1,2,4
grep echo /etc/asterisk/chan_dahdi.conf
echocancel=yes
echocancelwhenbridged=no
echotraining=yes
but it's never loaded:
# lsmod | grep echo
[root@asterisk ~]#
dahdi_cfg -vvv
DAHDI Tools Version - 2.10.0
DAHDI Version: 2.11.0
Echo Canceller(s):
Configuration
======================
Channel map:
0 channels to configure.
I can manually insert the oslec module using modprobe.
Thats seems to work.
CLI> dahdi show version
DAHDI Version: 2.11.0 Echo Canceller: OSLEC
But it's not persistent across reboots.

And even if I do manually load the oslec kernel module, I don't think
it's actually being used
cat /proc/dahdi/1
Span 1: WCTDM/4 "Wildcard TDM400P REV I Board 5" (MASTER)
1 WCTDM/4/0 FXOKS (In use)
2 WCTDM/4/1 FXOKS (In use)
3 WCTDM/4/2 Reserved
4 WCTDM/4/3 FXSKS (In use) RED
AFAIK, the echo canceller should show up here.
