Document Action: 'Telephony Signalling Transport over SCTP applicability statement' to Informational RFC

The IESG has approved the following document:

- 'Telephony Signalling Transport over SCTP applicability statement '
   <draft-ietf-sigtran-signalling-over-sctp-applic-09.txt> as an 
   Informational RFC

This document is the product of the Signaling Transport Working Group. 

The IESG contact persons are Jon Peterson and Allison Mankin.

Technical Summary

This document describes the applicability of the several protocols developed 
under the signalling transport framework[RFC2719]. A description of the main 
issues regarding the use of the Stream Control Transmission Protocol 
(SCTP)[RFC2960] and each adaptation layer for transport of telephony signalling 
nformation over IP infrastructure is explained.

Working Group Summary

The SIGTRAN WG supported the advancement of this Informational document.
