Hi,<div><br></div><div>I tried to get video working between one Grandstream and Polycom IP phone with H.264.</div><div>I&#39;m planning to make freeswitch as SBC for my internal network. </div><div>However, both proxy media a d pass-thru media are getting one way video. That is Polycom VVX can see Grandstream, not the other way.</div>
<div>I sniffer and found out that Polycom is doing inband SPS/PPS, so the first packet or so is for SPS/PPS, without this, the other-side cannot decode the video. </div><div>But freeswitch media proxy doesn&#39;t forward packets to right public address port until it receives packets from the other stream, which will trigger a RTP auto adjustment.</div>
<div>I just wondering is there any config to fix this or I have to modify the code? Thanks.</div>
