[reSIProcate] DNS blacklist/whitelist problem on resip 1.1 RC1

[Byron Campen]

	Well, these logs give me no indication of why the stack is  
blacklisting that tuple. The only reasons this should happen is
1) The remote endpoint sent a 503 with a Retry-After.
2) The remote endpoint timed out.
3) The transport to the remote endpoint failed.

	Since you are using UDP, my guess is 2, but I need to see more  
logging to be sure.

Best regards,
Byron Campen
