MIME media types for ISUP and QSIG Objects
RFC 3204, “MIME media types for ISUP and QSIG Objects”, is a Proposed Standard document published in December 2001 by E. Zimmerer, J. Peterson, A. Vemuri, L. Ong, F. Audet, M. Watson, M. Zonoun. It has since been updated by RFC 3459, RFC 5621. The canonical text is published by the RFC Editor.
Abstract
This document describes MIME types for application/ISUP and application/QSIG objects for use in SIP applications, according to the rules defined in RFC 2048. These types can be used to identify ISUP and QSIG objects within a SIP message such as INVITE or INFO, as might be implemented when using SIP in an environment where part of the call involves interworking to the PSTN. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
