[SR-Users] NO_DTLS_FINGERPRINT when calling from webrtc to webrtc client

Hi. Another topic about WebRTC, websockets with kamailio and rtpengine ;-)
My problem is how to distinguish a call to WS UAC and how to SIP UAC in
1) WS client1 -> WS kamailio -> SIP kamailio -> SIP UAC
2) WS client1 -> WS kamailio -> SIP kamailio -> WS kamailio -> WS client2
WS kamailio is a proxy, SIP kamailio is a registrar
When "WS client1" is calling to "123123" WS kamailio doesn't know if
"123123" was registered from "WS client2" or from SIP UAC.
I have in this case rtpengine_manage("....... RTP/AVP"), but when INVITE
is returned to WS kamailio? RTP/SAVPF?
Probably it is obvious, however...
When WS client2 reply with 200OK, rtpengine_manage("..... ICE=force") to
WS client1 SDP is sent without a:fingerprint. sipml5 dumps warning:
message: "Could not negotiate answer SDP; cause = NO_DTLS_FINGERPRINT
I tried different combinations... and I'm stuck :/
