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)

[Richard Barnes <[e-mail]>]

Is this really a conflict?  In the "c=" line, the addrtype is scoped to
either the "ATM" or "E164" nettype, so it's clear which one is meant.  I
think the only thing to do here is just have both RFC 3108 and this
document as references in the registry.
