[Freeswitch-users] Distorted sound when playing music into a conference

Hi, I noticed that when I place my phone on hold while I am in a conference,  and the phone plays music, the music is distorted to other conference members. I tried setting the "energy-level" parameter to zero, but it didn't help.  I also tried using "waste" but that did not help either. I know I can have the conference itself play hold music, but I would like to know how to configure the mixer to retransmit all the received packets.  I had thought the "waste" and "energy-level" should be enough to do this. How can I get the conference to retransmit all packets from the speaking member? Thanks, David
