Re: [serusers] calling problem - sr-users

24 Jun 2005

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> < 
http://sourceforge.net>gt;.
