Hi, See RFC 2915 (or RFC 3403). Within your example, it looks like record 10 would be selected.
"Low numbers are processed before high numbers, and once a NAPTR is found whose rule "matches" the target, the client MUST NOT consider any NAPTRs with a higher value for order (except as noted below for the Flags field)." "The important difference between Order and Preference is that once a match is found the client MUST NOT consider records with a different Order but they MAY process records with the same Order but different Preferences." > -----Original Message----- > From: sip-implementors-boun...@lists.cs.columbia.edu [mailto:sip- > implementors-boun...@lists.cs.columbia.edu] On Behalf Of Franz Edler > Sent: Sunday, August 02, 2015 5:53 AM > To: sip-implementors@lists.cs.columbia.edu > Subject: [Sip-implementors] Question about "order" parameter in NAPTR records > > Hi experts, I have the following question: > If I have two NAPTR records for the same FQDN with the same service but > different order (e.g. 10 and 20): > Does this mean that both records are processed (first 10 and the 20) with the > last one overwriting the result of the first? > Or does that mean that only the last one is processed? > > BR Franz _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
