Noise heard when a user holds a conference in SRTP mode
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
I'm going to guess your device method of placing you on hold is wrong. And possibly doesn't encrypt the data or doesn't signal a key change... is it white noise? /b On Apr 15, 2011, at 7:02 AM, Ujjwal SIngh wrote:

Yes Brian its a white noise, but the hold method works perfectly fine when used with RTP, the hold is implemented according to the draft http://datatracker.ietf.org/doc/draft-worley-service-example/?include_text=1 Regards, Ujjwal On Thu, Apr 21, 2011 at 3:13 AM, Brian West <brian@freeswitch.org> wrote:

Yah SRTP might NEVER work with that method of hold because now the MOH server and the endpoint have to exchange SRTP keys when you refer to them and they probably are NOT doing that right now which is why you get white noise. /b On Apr 21, 2011, at 6:26 AM, Ujjwal SIngh wrote:
