Hello,<br>
<br>
received and rport are added when the client is behind NAT. Can you
paste here the capture for the case that doesn't work? It will help
us to see what is wrong there, and if not, could be that the mobile
operator does some SIP ALG which breaks/blocks the sip, in this case
you have to switch to tls.<br>
<br>
Cheers,<br>

<div dir="ltr">I am using Kamailio 4.1.x with NAT enabled. When I
want to REGISTER using my desktop client which is Linphone
everything is find with any username. But on Android some users
can REGISTER and someusers can not. I captured SIP packets and
the only difference between packets on Android devices and
packets on Desktop client is that on my desktop "received" and
"rport" are not added by Kamailio in response messages. Any idea
on what is happening here?<br>
