Re: [MMUSIC] Protocol Action: 'Session Description Protocol (SDP) Extension For Setting Audio and Video Media Streams Over Circuit-Switched Bearers In The Public Switched Telephone Network (PSTN)' to Proposed Standard (draft-ietf-mmusic-sdp-cs-21.txt)

[Flemming Andreasen <[e-mail]>]

Hi Christian

We had a thread on this particular issue about a year ago. See

http://www.ietf.org/mail-archive/web/mmusic/current/msg09599.html

and the conclusion in

http://www.ietf.org/mail-archive/web/mmusic/current/msg09621.html

I hope this addresses your concern as it relates to -cs draft.

Thanks

-- Flemming
