Michael,
I'm quite certain that if the value of the "flags" column in the location table is set to 1 then the SER registrar module thinks that the REGISTER message is from a NATed client.
By default, SER uses flag 4 to indicate NAT status in the ser.cfg file. So if you have called setflag(4) somewhere before save("location") then you are informing SER that the client is NATed.
You can change the flag by using something like this
modparam("registrar", "nat_flag", 2)
The above line tells SER to use flag 2 as the NAT indicator.
Regards, Paul

it's impossible that it's that
first all my client are behind a NAT and some flags are 1 and others 0
second i 'm already used a stun server.
do you think that's something else?
do you know why after a specific time some SIP clients are deconnected alone? is there a variable that i can change for that?
thanks

Flags = 0 indicates that the SIP client is not behind a NAT device.
Flags = 1 indicates that the SIP client is behind a NAT device.
In order to get audio (ie, RTP streams) working one one or more SIP
clients
is behind a NAT device you must use either rtpproxy or mediaproxy.
The Getting Started document at http://onsip.org/ fully describes how to use both.
A third, but IMHO, less appealing option would be to use a STUN server, such as mystun which is availble at sourceforge.net http://sourceforge.net <
