It would definitely be useful to see sip traces of the different scenarios
to try and find what the problem is.
Can you give some details of what your setup looks like? Is kamailio acting
as a signaling proxy only or is it also handling RTP with
rtpengine/rtpproxy?

Thanks Joel For reply
when any user (Not Nated or behind Normal NAT) is trying to reach a
client behind CGNAT, the INVITE delivered and the client is start to
ringing, but when answering, the answer is not delivered to the proxy, so
not delivered to the calling client result to the call started in the
CGNATED client and still in establishing in the calling one.
The call is established successfully when the CGNATED send the INVITE to
Not Nated client and two way audio.
CGNATED to CGNATED not working as well .

Also, if the client is not behind CGNAT do you
get the Ringing from
called party?
Is called party the same in both cases?

Can you send the INVITE that proxy sends to
called party?

Hello
Although my question it's not related to Kamailio directly, but i think
someone could help in this strange behavior
in our tests, we have some clients under private networks, where the
provider of those networks implements CGNAT (NAT444) for it's customers to
reach internet
(Client Private IP) --->(Home router: Private to Private NAT)--->(FW
with CGNAT)---------------------------->(Kamailio Proxy Public IP)
Registration is performing fine, but making calls from this client had
strange problem as follow:
Client -------------INVITE--------------> Proxy
Proxy -------------Trying---------------->Client
Proxy--------------INVITE---------> Called Party
The called party should send Ringing msg, but the massage get lost
somewhere and didn't reach to the Proxy. Although all the IP's in sip
massages are public
i tried with STUN/TURN and NAThelper module solutions, but didn't help
is there any way to slove CGNAT with SIP in Kamailio?
Thanks in Advance
