Hi Nathan,

For Whitelisting - what do you mean about knowing all the hosts upfront?   I was referring to enabling the resip DNS Whitelisting feature - this doesn't require knowing anything up front.

I guess I don't understand how a record would get whitelisted. The DUM would get two records back from the SRV record, and try the first that would be grey listed because of a timeout. It looks like a path is whitelisted when there is a response that does not end in grey or black.

I guess I thought that because the 2nd record was never tried, you would need to add them to the whitelist before hand so that on the next request you would try the 2nd host first rather then the first timeout host.
