If there is no m=audio line for RTP/AVP the caller won't know of a port that's expecting RTP. So if the callee only sends SRTP/AVP the caller can't send RTP. Can you show us the SDP being sent by the phone? -Steve On 7 February 2013 11:01, Levend Sayar <levend.sayar@karel.com.tr<mailto:levend.sayar@karel.com.tr>> wrote: Thanx Steven. Caller makes the offer for SDP but callee chooses whatever it wants. So caller can offer SRTP but callee can prefer not to talk encrypted. In our case I want FS to choose non secure media. Phone will offer SRTP on the conference call but FS must prefer RTP, not SRTP.

I am using FS as a conference server. Some of my phones are using SRTP , some of them not. Both type of phone can join a conference. FS can talk to each peer with SRTP or not depending on the phone itself. My question: Is it possible to disable SRTP on FS ? I suppose if i can disable SRTP, FS will talk without SRTP with each phone whether they are using SRTP or not.
