 We have implemented this driver using Asterisk's RTP stack insted of trying
 to implement a pseudo sound card driver.

+NOTICE: Whatever you do, DO NOT USE distrubution specific installs
+of Open H.323 and PWLib. In fact you should check to make sure 
+your distro didn't install them for you without your knowledge.
+Check everything out of CVS. If you dont know how to deal with cvs, learn. 
+Also, if you are not using the listed versions of Open H.323 or PWlib

+versions ~should~ work.

+
+Most common compile error:  
+
+If you receive anything that says 'undefined symbol' you are experiencing
+typical version skew.  For example:
+
+libh323_linux_x86_r.so.1: undefined symbol: GetNumberValueAt__C14PAbstractArrayi
+
+You need to search and destroy every version of libh323 and libpt then 
+completely recompile everything
+
+Example commands to make sure everything gets cleaned and then
+rebult in proper order:
+
+cd /path/to/pwlib
+make clean opt
+cd /path/to/openh323
+make clean opt 
+cd asterisk/channels/h323
+make clean install   
+
+(Note: Open H.323 or PWLib never get a 'make install')
