[SR-Users] Problem with NATed UAC

[Vladimir Stepic]

Hello everyone,
this is my first message. I'm glad to become a part of this big community.
I'm new in SER technology. I worked in Asterisk PBX only, until now.
For the first time i installed Elastix MT witch have kamailio in front of
asterisk, and now i have a problem.
I attach a diagram of initial configuration in my lab and pcap file and
kamailio.cfg.
Regardless diagram, x.x.x.x addresses are public and y.y.y.y are private.
When i test connection 1.1 is working,
connection 1.2 not working
connection 2.2 not working
connection 1.3 not working
connection 2.3 working
Phones are connected(authenticate) to kamailio, but when i look at asterisk
cli those phones are unreachable, but can call, but can not be called.
On router where android works, Siemens dont, and where pc softphone works
other UAC dont work.
I think that my nat-traversal configure good, regardless of documentation.
Please tell me, if someone has some ideas of solve this problem.
Thanks in advance, and sorry for my bad english :)
