The IESG has received a request from the Sip ALerting for User Devices WG (salud) to consider the following document: - 'URNs for the Alert-Info Header Field of the Session Initiation Protocol (SIP)' <draft-ietf-salud-alert-info-urns-12.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-04-25. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Session Initiation Protocol (SIP) supports the capability to provide a reference to a specific rendering to be used by the UA when the user is alerted. This is done using the Alert-Info header field. However, the reference (typically a URL) addresses only a specific network resource with specific rendering properties. There is currently no support for standard identifiers for describing the semantics of the alerting situation or the characteristics of the alerting signal, without being tied to a particular rendering. To overcome these limitations and support new applications, a new family of URNs for use in Alert-Info header fields (and situations with similar requirements) is defined in this specification. This document normatively updates the RFC 3261, which defines the Session Initiation Protocol (SIP): It changes the usage of the Alert- Info header field defined in the RFC 3261 by additionally allowing its use in all provisional responses to INVITE (except the 100 response).
