Hi, I have FreeSwitch configured as a conference bridge, the sip_secure_media=true in dialplan and vars.xml. User A, B and C are in a conference, the media is established in SRTP mode, when any user presses hold, other members hear noise, while in RTP mode normal Music on Hold is heard. Can anybody please help what is going wrong in SRTP case. I have uploaded FreeSwitch log in pastebin below http://pastebin.freeswitch.org/16103 Thanks for the help. Regards, Ujjwal
