I am a little bit confused about the following statement in RFC 3263 chapter 4.1: If a SIP proxy, redirect server, or registrar is to be contacted through the lookup of NAPTR records, there MUST be at least three records - one with a "SIP+D2T" service field, one with a "SIP+D2U" service field, and one with a "SIPS+D2T" service field.
Some paragraphs before I can read: If the server supports multiple transport protocols, there will be multiple NAPTR records, each with a different service value. I understand, that three NAPTR records are the maximum for a given server, if it supports all three transport services. But that does not fit to the above mentioned clause stating "there MUST be at least three records...". Can anyone help me to understand this?
