asterisk users - Aug 2005 - unresolved symbol when loading ztdummy

Hi!

When I try to load the ztdummy driver via "insmod ztdummy", I get the 
following errors:
/lib/modules/2.4.26/misc/ztdummy.o: unresolved symbol zt_unregister
/lib/modules/2.4.26/misc/ztdummy.o: unresolved symbol zt_transmit
/lib/modules/2.4.26/misc/ztdummy.o: unresolved symbol zt_receive
/lib/modules/2.4.26/misc/ztdummy.o: unresolved symbol zt_register

I'm using zaptel-1.0.8 and a 2.4.26 kernel. Unfortunately I cannot change to
a
more recent kernel, and another drawback that I have is, that I cannot 
compile on the machine that Asterisk is supposed to run on. However I booted 
my development machine with a 2.4.26 kernel and the compilation went well. 
What I am actually trying to archive is, getting the ztdummy driver to work in 
order for my Asterisk machine to do IAX2 calls. As far as I have understood 
it this is necessary if I don't have any Digium hardware.
What is the problem that I'm having and how can I fix it?

Thanks a lot,
Christoph

You also need to load the "zaptel" module, not just ztdummy.

ztdummy shouldn't be needed for IAX2 unless you are using trunking.

Your kernel has to be compile with CONFIG_CRC_CCITT=y or m.
