Answer 1

found solution

_conversation.ConferenceSession.AudioVideoMcuSession.ParticipantEndpointAttendanceChanged += OnMCUAttendanceChanged;

and write fuction

private void OnMCUAttendanceChanged(object sender,
                                                    ParticipantEndpointAttendanceChangedEventArgs<
                                                    AudioVideoMcuParticipantEndpointProperties> e)
        {
            foreach (KeyValuePair<ParticipantEndpoint,
            AudioVideoMcuParticipantEndpointProperties>
            pair in e.Joined)
            {
                Console.WriteLine(string.Format("{0} joined the MCU.",
                pair.Key.Participant.Uri));
            }
            foreach (KeyValuePair<ParticipantEndpoint,
            AudioVideoMcuParticipantEndpointProperties>
            pair in e.Left)
            {
                Console.WriteLine(
                string.Format("{0} left the MCU.",
                pair.Key.Participant.Uri));
            }
        }

This is not real read participant list of current conference, but i can catch "Left" event and create rejoin function with Uri telephone number
