Summary: DAHDI_ATTACH_ECHOCAN failed on channel 1: Invalid
argument(22)
Description:
On Gentoo, it appears that the kernel is not configured to allow auto
loading of modules. This prevents the DAHDI_ATTACH_ECHOCAN from loading
the software echo canceler requested in the /etc/dahdi/system.conf file,
and the result is an error like:
"DAHDI_ATTACH_ECHOCAN failed on channel 1: Invalid argument(22)"
To work around this the "dahdi_echocan_<name of echocan>" could be added
to /etc/dahdi/modules
I.e. If you have mg2 configured as the echo canceler in
/etc/dahdi/system.conf, add the line "dahdi_echocan_mg2" to
/etc/dahdi/modules.

mancy: You must be hitting something different if just switching to mg2
fixed the problem for you. My guess is that OSLEC wasn't built properly.
Try just 'modprobe dahdi_echocan_oslec' and see what errors, if any, show
up when running dmesg.
