<div style="">This is a rather broad assumption. I have seen 40ms, 60ms and even 80ms in the wild. It all depends on what you want to do. It lowers overhead and increases efficiency on the wire.<div><br></div><font color="#888888"><div>

Here IPO is unable to negotiate a different framing size than the default and sadly this is the core of the problem.<br>
<br>Please, can you send me two tcpdump captures of calls between IPO and FS:<br><ol><li>a capture with fast start & h245tunneling=true</li><li>a captire with fast start & h245tunelling=true + h245inSetup</li></ol>
<br>I just want to be sure of something.<br><br>T.<br>
