asterisk users - Sep 2005 - ztdummy configuration help

Upon setting up and configuring the my extension.conf, meetme.conf and
following the instruction outlined at this web page:
http://www.voip-info.org/wiki-Asterisk+timer+ztdummy

I get the following errors when calling the meetme number.

Executing Wait("SIP/216.53.118.2-f41196e0", "1") in new
stack
    -- Executing MeetMe("SIP/216.53.118.2-f41196e0",

Any help is greatly appreciated.

The device /dev/zap/pseudo (and probably ctl, timer, channel) is
missing. Asterisk process needs write permissions for this device.

If you are using kernel 2.6 and udev check README.udev (as described
in the wiki mentioned in your mail)

Hi Kurt,

I had the same problem, it seems that asterisk requires a timer for meetme() 
app to work. You need to install ztdummy.o module into the kernel and then 
restart asterisk.

Next obvious question will be, where do I get ztdummy??

Well, If you open the Makefile in zaptel source directory on line number 61 
you will see ztdummy commented. Please uncomment that and run make and then 
make install, this will put the ztdummy.o module into appropriate place in 
/lib/modules/........

After that do a modprobe ztdummy and then restart asterisk.

That is it. You are ready for conference calls.

BTW here is what i am using.

zaptel-1.0.9.2
libpri-1.0.9
asterisk-1.0.9
Kernel version 2.4.18-14
