RFC 6228, "Session Initiation Protocol (SIP) Response Code for Indication of Terminated Dialog", May 2011

Errata ID:4886
Status: Reported
Type: Technical
Publication Format(s) : TEXT
Reported By: Brett Tate
Date Reported: 2016-12-13

Section 5 says:

   If the Supported header field of an initial dialog initiation request   does not contain a "199" option-tag, the UAC MUST NOT send a 199   response on any early dialog associated with the request.

It should say:

   If the Supported header field of an initial dialog initiation request   does not contain a "199" option-tag, the UAS MUST NOT send a 199   response on any early dialog associated with the request.

Notes:

Changed "UAC" to "UAS" since the UAC does not send responses.
