[Freeswitch-users] crypto tag in sdp in webrtc INVITE message

Hi All, Need some clarification here. It seems that by default Freeswitch will use DTLS in webrtc. According to this http://tools.ietf.org/html/rfc4568, crypto tag is used by SDES. And according to this https://bugzilla.mozilla.org/show_bug.cgi?id=825515, crypto tag shouldn't be in the SDP. Is it correct to have crypto tag in SDP when we use DTLS? FYI, I have made some modification to jssip and make it works with firefox 23 & Freeswitch https://groups.google.com/forum/#!topic/jssip/wXWrcBYHJ28 But it only works when the call initiated by firefox. It gives me no audio when the call initiated by SIP phone or using originate command. And i guess one of the causes is this crypto tag existence. Thanks. -- Iwan Budi Kusnanto
