Hello,

First of all i would like to say i am a newbee in Kamailio :).

Here is my network configuration :

User 1 User2 10.10.10.3 10.10.10.2 192.168.0.2 192.168.0.10 -----------------*KAMAILIO*-----------------

User1 and User2 are registered in mysql. When i installed Kamailio, i edited kmctlrc to have SIP_DOMAIN = 10.10.10.2.

I am using XLite Siphone for both users. When User 1 is registering to Kamailio there is no problem, but when User2 try to do the same i get 407 Proxy Authentication Required..

What i would like to do is User1 call User2 trough kamailio. Obviously i activated nathelper module and started rtpproxy. Do i need to configure multi-domain module ?

Here is my .conf file :
