Definition of Events for Modem, Fax, and Text Telephony Signals
RFC 4734, “Definition of Events for Modem, Fax, and Text Telephony Signals”, is a Proposed Standard document published in December 2006 by H. Schulzrinne, T. Taylor. It updates RFC 4733. It obsoletes RFC 2833. The canonical text is published by the RFC Editor.
Abstract
This memo updates RFC 4733 to add event codes for modem, fax, and text telephony signals when carried in the telephony event RTP payload. It supersedes the assignment of event codes for this purpose in RFC 2833, and therefore obsoletes that part of RFC 2833. [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.
The canonical text of RFC 4734 is hosted at rfc-editor.org. Available in TXT,HTML.
