Hi all, In order to solve the remaining issue of the draft http://tools.ietf.org/html/draft-ietf-avt-app-rtp-keepalive-03 (cf details at http://www.ietf.org/mail-archive/web/avt/current/msg09656.html ), we would like some feedback from the MMUSIC WG. The issue is the following: When rtcp-rtp-mux can not be negotiated, there is a need for an agent to send rtp-keepalive (RTP packets containing no media) without consulting the remote agent (ie: no need for offer/answer negotiation). Some people indicated they would like to see this feature indicated in the SDP. We would thus like to know whether it would be acceptable that an agent add an optional a=rtp-keepalive SDP attribute in order to indicate that it will send rtp-keepalive when rtcp-rtp can not be negotiated. Cheers, Xavier _______________________________________________ mmusic mailing list mmusic@ietf.org https://www.ietf.org/mailman/listinfo/mmusic
