Problem with parallel forking - sr-users

21 Jan 2011


      Hi all,
I'm using kamailio 3.1 and I have some problems with parallel forking.
I need to implement parallel forking to different users registered on
kamailio.
So, when call arrives with R-URI= sip:003912345678@<IP_server>, I need
to fork te call to (for example) 2 users: 1001 and 1001.
To do that, I've created my usr_preferences table like this:
+----+------+------------------+--------+-----------+------+-------+---------------------+
|/ id | uuid | username 	       | domain | attribute | type | value | /last_modified       |
+----+------+------------------+--------+-----------+------+-------+---------------------+
|/  1 |      | /003912345678/     |        | fork      |    0 | 1001  |              |
/|/  2 |      | /003912345678/     |        | fork      |    0 | 1002  |              |
/+----+------+------------------+--------+-----------+------+-------+---------------------+
and I've added a code to my kam.cfg like this:
if (is_method("INVITE")) 
{
    
    xlog("L_INFO", "REQUEST Invite - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
        if(avp_db_load("$ru/username","$avp(s:fork)"))
        {
            avp_pushto("$ru/username","$avp(s:fork)/g");
}
    
    if(!lookup("location"))
        {
xlog("L_INFO", "Local user offline - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
                sl_send_reply("404", "User Offline");
                exit;
        }
        else
        {
xlog("L_INFO", "Local user online - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
                t_relay();
        }
}
If 1001 and 1002 are registered everything works fine (1001 Ringing and
1002 ringing).
Ifonly 1001 registered everything works fine (1001 ringing and 1002 is
offline.).
But when 1002 is registered and 1001 in offline, kamailio try to call
1001, find that it's offline ( and I get 404 User Offline") but no call
to 1002 is attempted.
What's wrong ?
Regards,
Daniel
