<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">“ the term "valid telephone number" refers to a telephone number that is a nationally specific service number (e.g., 611, 911), or a telephone number that can be converted into a globally routable E.164 number, as specified in section
8.3 of [RFC 8224].”<o:p></o:p></p>

<p class="MsoPlainText">From the RFC (<a href="https://datatracker.ietf.org/doc/html/rfc8224#section-8.3">https://datatracker.ietf.org/doc/html/rfc8224#section-8.3</a>)<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Implementations MUST drop any "+"s, internal dashes, parentheses,<o:p></o:p></p>
<p class="MsoPlainText">or other non-numeric characters, except for the "#" or "*" keys<o:p></o:p></p>
<p class="MsoPlainText">used in some special service numbers (typically, these will appear<o:p></o:p></p>
<p class="MsoPlainText">only in the To header field value). This MUST result in an ASCII<o:p></o:p></p>
<p class="MsoPlainText">string limited to "#", "*", and digits without whitespace or<o:p></o:p></p>
<p class="MsoPlainText">visual separators.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In looking at the examples in ATIS-1000074-E, this doesn’t mean that the + should be removed from the other SIP headers (To:, From:, etc), but apparently it shouldn’t be in the jwt of the Identity header.<o:p></o:p></p>
