Hello guys,
I have this setup:
Zoiper-->Kamailio->fs->kamailio->webrtc client(s)
Whenever webrtc clients call each other, calls are ok.
But when the zoiper (regular sip/tcp) calls, the browsers complaint about:
"no ice-ufrag" (firefox) or
"Failed to set remote offer sdp: Called with SDP without DTLS fingerprint." (Chrome).
I am setting the sdp in freeswitch as:
<action application="set" data="proxy_media=false"/>
<action application="set" data="bypass_media=false"/>
<action application="export" data="zrtp_secure_media=false"/>
<action application="export" data="nolocal:rtp_secure_media=true"/>
and the actual sdp is:
v=0

s=FreeSWITCH
c=IN IP4 1.2.3.4

I'm pretty new to the webrtc stuff, so any help is greatly appreciated!
Thanks!
