[sr-dev] [kamailio/kamailio] 5.1.2: rtpengine module hijacks DTLS key (#1468)

### Description rtpengine module is hijacking the DTLS key rtpengine_manage("DTLS=off") DTLS=off is a valid command to rtpengine, but the module uses that flag to set transport as UDP/TLS/RTP/SAVP Unfortunately even though the transport can be fixed by RTP/SAVP, the lines outputted by rtpengine a=setup:actpass a=fingerprint:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx confuse some UACs that were expecting only SDES. FreeSWITCH is affected. ### Troubleshooting #### Reproduction rtpengine_manage("DTLS=off"). tcpdump the traffic between kamailio and rtpengine. Obseve that there is no DTLS=off key. #### Debugging Data #### Log Messages #### SIP Traffic ### Possible Solutions Don't look for DTLS key, let that be passthrough to kamailio ### Additional Information 5.1.2 * **Operating System**: Linux CentOS 7.4 -- You are receiving this because you are subscribed to this thread.
