<br></pre></blockquote><div>I don't understand. Are you saying that you have clients that when they receive an invite sent video with 183? How do you want to composite the video to show to the caller? It is not RFC3261 compliant to change IP and port from 183 to 200. Of course you can reinvite after the 200. Most B2BUAs require you to ignore early media and generate something locally to send to the caller or just send them 180.</div><div><br></div><div>Maybe if you explain your use case someone can help you.</div><div><br></div><div>--FC</div><div><br></div><div><br></div></div></body></html>
