<div>kamailio will recive two REGISTER at a time.In first 200
OK to REGISTER, Server will tell Linphone the Linphone Nat
Ip and Port.</div>
<div>like this:</div>
<div>Via:SIP/2.0/TCP
30.9.2.1:50691;received=42.1.7.1;alias;branch=z9hG4bK.kmhC2L9Rf;rport=33746</div>
<div>and Linphone will know it's outside nat Ip and port,
Linphone while use this Ip and Port in second REGISTER.</div>
<div>like this:</div>
<div>REGSITERÂ </div>
<div>Contact:<a><sip: 42.1.7.1:33746;transport=tcp></a></div>
<div><br>
</div>
<div>So kamailio server know Linphone's nated ip and port and
save in DB(contact field).</div>

<div bgcolor="#FFFFFF" text="#000000"> Indeed, the ports are
different, that's why adding received is important in this
situation.<br>
<br>
While local ip and local port are in most of the cases
also unique for devices behind a nat router, it is not
100% true, because there can be many layers of NATs, which
can result in seeing same local ip/port for devices.<br>

Because both devices are behind the same
NAT, practically they show the same source
IP when they send traffic to server.<br>
