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

[Iwan Budi Kusnanto]

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.
