Re: [SR-Users] Kamailio sending NOTIFY messages to private IP

Hello,

have you used set_contact_alias() or fix_nated_contact() for SUBSCRIBE?

Cheers, Daniel

Hello,

Im running kamailio 4.2.3 and I'm having troubles with reporting user presence data from Kamailio server to a registered UA behind nat. The NOTIFY message is being sent from Kamailio to the UA after receiving PUBLISH, but because the UA is behind nat the NOTIFY message is being sent to the UAs private (=unroutable) ip and therefor never reaching the real UA. My server is using nat helping modules so that REGISTER messages and INVITE messages are handled ok even if they are originated behind nat.

Any suggestions how to solve this and make the NOTIFY messages to be sent via routabe ip addresses?

my kamailio.cfg PRESENCE routing:

#!ifdef WITH_PRESENCE if (!t_newtran()) { sl_reply_error(); exit; };

if(is_method("PUBLISH"))
{
    handle_publish();
    t_release();
}
else
if( is_method("SUBSCRIBE"))
{
    handle_subscribe();
    t_release();
}
exit;

#!endif

if (is_method("PUBLISH") || $rU==$null)
{
    sl_send_reply("404", "Not here");
    exit;
}
return;

}
