:-) Thanks, now I understand. See inline.

Thanks for answering ;)

Using ser.cfg from onsip.org version 5.

When Uas register to ser, they are register with their privates IPs (192.168.xxx.xxx), not with the public Ip of the natted network.

So serctl ul show will show the private address for the UA? If so, for some reason the client_nat_test does not detect the NATed client, an ngrep of the registration will help.

Making a call requires proxy authentification but ser WWW-Challenge never arrives to UA(wrong adress).

The challenge is not sent to the registered address, but rather to the originator of the request. An ngrep trace of the INVITE will again help. The challenge response will normally be sent to the source ip and port, not the contact (which BTW also should be fixed by calling fix_nated_contact())

In tha cfg, I have :

if (method=="INVITE" && client_nat_test("7")) {
  # INSERT YOUR IP ADDRESS HERE
  record_route_preset("82.146.xxx.xxx:5060;nat=yes");
} else if (method!="REGISTER") {
  record_route();
};
and also :

if (!search("^Contact:[ ]*\*") && client_nat_test("7")) {
  setflag(6);
  fix_nated_register();
  force_rport();
};

if (!www_authorize("finalcut.be","subscriber")) {
www_challenge("finalcut.be","0");
break;
};

You complained about no one answering your questions. An advise: When writing a question, please state clearly what you want to accomplish, what the problem is, and as much information about the problem as possible.

I have rechecked some of your recent posts, they are all in telegraph language, and I find it very hard to understand what your question really is.

To be honest, the below question really makes no sense to me.

Subject: [Serusers] mediaproxy and private ip

Using the last cfg from onsip.org, i just see that now Uas are registered with their private Ip when using mediaproxy.

Mediaproxy seems the best solution for scalability, that's why I want to test it.
