the only reliable answer is use TCP.<br><br>The RFC is daft in this matter.<br>They say when it's bigger than mtu to automatically use TCP instead.<br>And timeout for 10 seconds then fall back to UDP.<br><br>Its mandatory in SIP to support both TCP and UDP up to 64k per packet.<br>
As you can see, since barely anything will do this right, your best bet is to only use TCP when you have this kind of traffic.<br><br><br><div class="gmail_quote">On Tue, Nov 18, 2008 at 5:52 AM, Saurabh Aggarwal <span dir="ltr"><<a href="mailto:saurabh_aggarwal@hotmail.com">saurabh_aggarwal@hotmail.com</a>></span> wrote:<br>

Thanks, how do I "enable" this in freeswitch? Can this be done through the SIP configuration file?<br>
