Thank you Daniel,
That was what I was looking for.
Cheers,

Hello,
the problem is that lookup(location) is handling only R-URI,
so if ruri is for user XYZ and that is offline, then will return
false.
Since you create many branches with avp_pushto(), other
destinations added as extra branches will be not attempted
because of lookup(location) condition.
The best is to relay the call after the avp_pushto(), so you
will get two branches (or more) coming back via loopback and
then you do lookup location for each:
if(src_ip!=myself)
{
if(avp_db_load("$ru/username","$avp(s:fork)"))
{
avp_pushto("$ru/username","$avp(s:fork)/g");
t_relay();
exit;
}
}
if(!lookup("location")) ....
Be sure you skip authentication or other checks when the
requests comes back due to such loop, using if(src_ip==myself)
conditions.
Cheers,
Daniel

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).
If only 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
