Well, for one thing I don't have any spare registered domain names and 
for another keeping up with domains, finding dns servers, etc. seems 
like more work than it's worth, that is if I understand what you are saying.

I tried that.  It didn't work.  So I went off reading about 
masquerading.  It seems this might work too:

MASQUERADE_AS(`adsl-065-xxx-xxx-xxx.sip.asm.bellsouth.net')

But it didn't. 

I looked in the .cf file and as far as I could tell, the info got into 
it OK.

What exactly are the 'dnl' tags?  I figured they are comment delimiters, 
but why at both the beginning and the end?

Thanks,
Jim.
