The following errata report has been submitted for RFC8224,
"Authenticated Identity Management in the Session Initiation Protocol (SIP)".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6499

--------------------------------------
Type: Technical
Reported by: Marc Petit-Huguenin <marc@petit-huguenin.org>

Section: 4

Original Text
-------------
Identity = "Identity" HCOLON signed-identity-digest SEMI
          ident-info *( SEMI ident-info-params )
signed-identity-digest = 1*(base64-char / ".")
ident-info = "info" EQUAL ident-info-uri
ident-info-uri = LAQUOT absoluteURI RAQUOT
ident-info-params = ident-info-alg / ident-type /
    ident-info-extension
ident-info-alg = "alg" EQUAL token
ident-type = "ppt" EQUAL token
ident-info-extension = generic-param

base64-char = ALPHA / DIGIT / "/" / "+"


Corrected Text
--------------
Identity = "Identity" HCOLON signed-identity-digest SEMI
          ident-info *( SEMI ident-info-params )
signed-identity-digest = 1*(base64url-char / ".")
ident-info = "info" EQUAL ident-info-uri
ident-info-uri = LAQUOT absoluteURI RAQUOT
ident-info-params = ident-info-alg / ident-type /
    ident-info-extension
ident-info-alg = "alg" EQUAL token
ident-type = "ppt" EQUAL token
ident-info-extension = generic-param

base64url-char = ALPHA / DIGIT / "-" / "_"


Notes
-----
RFC 8225 makes it clear that the encoding is BASE4URL, not the standard BASE64 encoding.
