A new version is available of the overview of possible solutions for multi-party rtt. There is added detail in the section on RTP translator model alternative in section 4.1.2.1. This was done by inspiration from draft-ietf-avtcore-multiplex-guidelines/ /Gunnar Den 2020-06-19 kl. 20:43, skrev internet-drafts@ietf.org: > A New Internet-Draft is available from the on-line Internet-Drafts directories. > > > Title : Real-time text solutions for multi-party sessions > Author : Gunnar Hellstrom > Filename : draft-hellstrom-avtcore-multi-party-rtt-solutions-02.txt > Pages : 43 > Date : 2020-06-19 > > Abstract: > This document specifies methods for Real-Time Text (RTT) media > handling in multi-party calls.
