<div dir="ltr"><div><div><div><div>Hi,<br><br></div>My idea is to modify the entire RTP packet and send a customized packet to the Mediaproxy/Server. <br><br>After the customization is reverted back then the normal routing will be performed by media proxy.<br>
<br></div>then just before transmission customization will be done to RTP packet again and send to the client.<br><br></div>I have almost full control over client, but Server - I dont have much control over it..<br><br></div>

</div></div>As soon as one RTP packet is received from each endpoint MediaProxy will create a conntrack rule in the kernel, which will do the relaying. At that moment MediaProxy no longer has access to the actual packets, as they are being handled by the kernel.<br>
