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.
