Re: [reSIProcate] RFC 3263, reSIProcate vs sipX

[Byron Campen <bcampen@xxxxxxxxxxxx>]

	I have recently done some work on the resip DNS code to get it up to  
snuff. testDns is much, much bigger now, but it needs a test DNS zone- 
file to be set up in a very particular way for it to work. I want to  
try to have this done sometime this week.

	As for isolating the DNS code, you will need to pull a lot of rutil  
with it. Also, you'll need resip/stack/DnsResult.[hc]xx (where all  
the 3263 logic is) and resip/stack/DnsInterface.[hc]xx to make it all  
go. I know for sure this drags resip/stack/Tuple.[hc]xx in as well,  
and possibly other stuff.

Best regards,
Byron Campen
