All of my clients are behind NAT! Unfortunately I can not put my captures
here. The strange thing here for me is that:
1- Desktop can always REGISTER with all of my usernames.
2- My android phones can REGISTER with some usernames! For example if I
have a 12 and a 17 username Android Linphone can REGISTER with 12 but not
with 17. Kamailio will always return a 401 error. This thing only happens
on Android Linphone.
I captured packets for both scenarios but nothing is strange about packets!
How is this even possible?!!

Hello,
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.
Cheers,
Daniel

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?
