Hello,<br>
<br>
the BYE does not have information about the public ip of the nat
router behind which is located the android device.<br>
<br>
With the default config of kamailio, that should be stored as alias
parameter in the contact header.<br>
<br>
You should send the full signaling from first invite to the bye for
the case that does not work, in order to see if something goes wrong
there and what party is responsible for that.<br>
<br>
You should use ngrep to take the trace on kamailio server, because
it easy to read and captures the both sides. A sample command would
be:<br>
<br>
ngrep -d any -qt -W byline port 5060<br>
<br>
Of course you can replace IP addresses with suggestive tokens.<br>
<br>
Cheers,<br>
Daniel<br>
