Domain Policy DDDS basics
The domain is the key to the destination policy
Use the DNS as rule store
No special translation rules necessary
Infrastructure is in place
Example:
example.com. IN NAPTR 10 50 "U" "D2P+SIP:fed" "!^.*$!http://sipxconnect.example.org/!" .
“Regarding SIP, example.com is a member of the federation identified by this URI.”
Non-terminal NAPTR for customer domains referring to provider domains
Protocol agnostic
SIP is just a special case
