+#define SIP_PAGE2_UDPTL_DESTINATION		(1 << 24)  /*!< DP: Use source IP of RTP as destination if NAT is enabled */

Perhaps I shouldn't've checked the ship-it ;)

There is no conceivable way that someone would write code that requires a provisional 100 response to a REGISTER. It would be an absurd amount of going out of one's way to write broken code. Add to that the fact (as wdoekes points out on the mailing list) that the flag is set on the peer, not copied to the pvt, but checked on the pvt anyway--it hasn't even worked all these years.
