Hi, 1. Is it possible to create ipv6 <=> ipv4 media proxy from FreeSwitch? So i need to mangle SDP to replace ipv6 to ipv4 and vice-versa. (but i use fnacy things like BFCP,FECC(H.224),secondary video) 2. Further more I need to know that FreeSwitch can function as a real media proxy? So can it PROXY as MEDIA like BFCP(TCP!), FECC and secondary video? 3. Can i use more than one stream so more than 1 audio + 1 video stream in a sip call in proxy media mode? For example 1 audio + 2 video stream (people+presentation) Example SDP piece for BFCP, and FECC(H.224): m=application 49158 RTP/SAVP 100 a=rtpmap:100 H224/4800 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:lv6Y5eO/RSDDOFNvbFmM0q9tfrt3/ZxXqPJx4Pj5|2^31 m=application 0 TCP/BFCP * a=floorctrl:c-s a=setup:actpass a=connection:new Any help highly appreciated! Thanks, Misi
