ITU-T Question 7/15, (Voice Gateways), is developing new ITU-T
Recommendation G.799.1, covering functionality, interfaces, performance
requirements and functional tests for voice gateways interfacing GSTN to IP
networks. The current text of draft G.799.1 is available on Q7/15's IFA web
page at: 

http://ties.itu.int/u/tsg15/sg15/wp2/stable_text/gtigin/

The latest version (approved at the SG15 meeting in Geneva, October 2001)
is V6.0

At the recent Geneva meeting text was approved for inclusion in the
document for defining the handling of Signalling System No.7 associated
signalling links by a TIGIN gateway. Q7/15 would appreciate the comments of
both SG11 and IETF Sigtran on the text included in sections 3.3.2.3.1
(Signalling Backhaul for Signalling System No. 7) and 3.4.1 (SS7 Signalling
Links).

In addition Q7/15 would appreciate the views of SG11 on the suitability of
the IETF Sigtran protocols for this application.
In addition Q7/15 request IETF Sigtran to clarify the status of the Sigtran
protocols, in particular the stability of RFC 2960bis (SCTP) (May 16, 2001)
and the likelihood and timing of draft-ietf-sigtran-m2ua-10 (M2UA)
achieving full RFC status.
