I would start by evaluating your design, you can get start-talking and stop-talking events from the event socket for the conference, you shouldn’t need to call in for that. https://freeswitch.org/confluence/display/FREESWITCH/mod_conference#mod_conference-EventSocketUse

Hi Users,
I want to get the VAD events on a conference call, i want to join a conference call silently and just wanted to get vad events.
What i did is to land the conference call in a context and run echo application.(as vad events appears on b leg)
But that caused noise in conference, so i droped the rtp packets using iptables rules.

Problem: Everything works great, but now i want to traverse in conference(like pin etc) and i send dtmf 2833 which also get droped by iptables.

Question: is there a way i can get vad events and be as a silent listener of conference as well.

P.S: previously i used originate conference and landed on park(), but that do not generate vad events. So i switched to echo()
