[asterisk-users] modprobe Ztdummy is not working

[Jean-Etienne Kelly]

Hi,

I've install zaptel and I don't have a Digium card installed in the machine.
So I want to install ztdummy to have Music On Hold working. I've follow
these instruction http://www.voip-info.org/wiki-Asterisk+timer+ztdummy and
at the point "modprobe ztdummy" it's failing. I'm getting these messages: 

root at dubic:~# modprobe ztdummy
FATAL: Error inserting ztdummy (/lib/modules/2.6.17.6/misc/ztdummy.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error running install command for ztdummy

After doing dmesg I'm getting this:

I have Kernel 2.6.17.6, and zaptel 1.2.10.

What do you thing about this?
Thanks
