You need send reply with Reverse rtp_manage functions. Now you sending with hte same handling as request going to Kamailio. You use WS-UDP handling for inwite and WS-UDP handling for reply. You must use WS-UDP to requests and UDP-WS to replyes

Hello list! Have some difficulties with RTPengine: My test scheme is: UA(WS) -> Kamailio (WS proxy) -> Kamailio (SIP REGISTRAR, proxy) -> ASTERISK (media server) -> UA (SIP) Kamailio (WS) use RTPengine.
Kamailio (WS proxy) - 4.2.3 Kamailio (SIP REGISTRAR, proxy) - 4.1.4 RTPengine - 3.3.0.0+0~mr3.8.0.0
I make a test call and have troubles in negotiation between UA(WS) -> Kamailio (WS proxy): UA(WS) -> INVITE -> Kamailio WS ...... rtpengine_manage("trust-address replace-origin replace-session-connection ICE=force"); ...... this INVITE consists in SDP section a=fingerprint:sha-256......
When Kamailio (WS) receives 200 OK, it is also handled by RTPengine ....... rtpengine_manage("trust-address replace-origin replace-session-connection ICE=force"); ....... but UA (WS) receives 200OK without fingerprint, and log an error:
Failed to set remote answer sdp: Called with SDP without DTLS fingerprint.
Currently spend a lot of time reading Kamailio/RTPengine documentation/mail-list - but without success If someone have some hints, I would appreciate any help.
