[Asterisk-Users] unresolved symbol when loading ztdummy

[Christoph Eicke]

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
