[Freeswitch-dev] Sending RTP data without SIP

Hello All, Recently, I am having fun with freeswitch. I need to implement a module, which sends RTP data to previously specified IP and PORT. I do not want to have SIP/SDP session. Which is the best or just good enough way to do that? I understand my module should act as an endpoint then I need probably would need to create the session object, set the needed codecs, load (for example) the desired file for playing and start sending RTP. I had some debugging actions on freeswitch and found that functions sofia_glue_negotiate_sdp, sofia_glue_tech_choose_port are dealing with local and remote site of RTP connections. Could you advice me ?
