I noticed a difference between ser and asterisk. <br>When a phone send a register packet with src port 30001, dst port 5060 and &quot;via:x.x.x.x:32001&quot;, <br>ser will response a 200 response with &quot;src port 5060, dst port 30001 and &quot;via:
x.x.x.x:32001&quot;, but<br>asterisk will response a 200 response with &quot;src port 5060, dst port 32001 and &quot;via:x.x.x.x:32001&quot;<br><br>Don&#39;t know why they make this difference? which one more obey the sip standard? 
<br><br>thanks.<br clear="all"><br>-- <br>Rgds, <br><br>Hans Yin<br>Web: <a href="http://homeofhans.homeip.net">homeofhans.homeip.net</a><br>Email: <a href="mailto:hansyin@gmail.com">hansyin@gmail.com</a> <br>MSN: <a href="mailto:hansyin@hotmail.com">
