Hi friends As of now when we mute a participant, conference server mutes that participant while RTP keeps on coming from that UA. This consumes the bandwidth & precessing time also is there. This issue elobrates when no. of conference participants are increased. So I am just wondering whether we can mute the conference participants using the SIP SDP `reconly' & whenever we wants to unmute him, FS should again send the INVITE SDP with `sendonly'. Plz let me know if it is feasible. Thanks in advance. regards Sharad
