2.2.10 Ms-Sensitivity Header Field Syntax

This protocol defines a header field called Ms-Sensitivity to indicate if a call can be directed to another person or diverted to another device representing the same person. The ABNF, as defined in [RFC5234], for this header is as follows:

Ms-Sensitivity = "Ms-Sensitivity" HCOLON ("normal" / "private" /
                 "normal-no-diversion" / "private-no-diversion")

A sensitivity of "normal" MUST be assumed if the Ms-Sensitivity header field is not present. If the header field contains a value other than one of those specified or appears more than once, a 400 response SHOULD be returned.

HCOLON is defined in [RFC3261] section 25.
