<div>Dear Klaus,</div><div><br></div><div>Thank you for your email.</div><div>I tried using my UA connecting to the servers provided by other free sip service provider like Opensips in WAN.</div><div>And the same problem didn't happen. My UA did sent ACK after the 200 OK in the invite process.</div>
<div><br></div><div>It looks like the problem is my Kamailio server 's NAT setting.</div><div><br></div><div>I wonder how I can do to verify whether the NAT setting is correctly done. What kind of method did you use in this issue?</div>
<div><br></div><div>Your help will be great appreciated.</div><div><br></div><div>Coca</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><br><br><div class="gmail_quote">2011/7/21 Klaus Darilion <span dir="ltr"><<a href="mailto:klaus.mailinglists@pernau.at" target="_blank">klaus.mailinglists@pernau.at</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">IF you take a look at the trace you see, that the caller does not send<br>
ACK after receiving 200 OK. Either it does not send ACK or it sends it<br>
to wrong destination.<br>
<br>
Trace at the caller's phone and watch log file of caller.<br>
