Entering 'iax2 debug on' at the command line gets a "no such command' 

There is no response to the 'accept' on teh console,  but I do see 
'circuit is busy' followed by 'Auto-congesting call due to slow 
response' as if it did not see the 'accept' at all.

I agree with the fact that the iax source code being  the protocol 
documentation is a very poor practice.  I come from a 
military/industrial/automotive background where that would be just plain 
unacceptable.  It's really making me second-guess my decision to go with 
iax for this project.

Thanks again,
