These configurations all assume you have done "make samples" in your asterisk source directory.
These are also the MOST COMMON configurations, so don't completely depend on them to work with what you are doing.
Pat loop test
Edit zaptel.conf and put the channels in clear
run patlooptest /dev/zap/1
to generate the tests do "make tests" in the zaptel source.
Send all 0's to channels (not sure why)
in zaptel.c change the following:
", 0xff" to ", 0"
Lower flash timing
in zaptel.h change the value 150 to 75
#define ZT_MAXPULSETIME (150 * 8)
Follow the README in the channel driver
Put the pwlib and openh323 source in your /root dir to make things simpliar
You will need to export these variables and add it to /etc/profile
Add this to your /etc/ld.so.conf
Then run "ldconfig"
then compile the channel driver
