Hi all,
I'm trying to implement parallel forking to different users registered
on a Kamailio server. I want to fork the call to a number of different
users (not including the called user).
To do this I added the piece of code below to the default 3.0.0 config
file:
...
# account only INVITEs
if (is_method("INVITE")) {
setflag(1); # do accounting
setflag(4); #dialog aware
if(avp_db_load("$ru/username","$avp(s:fork)"))
{
avp_pushto("$ru/username","$avp(s:fork)/g");
};
}
....
This is usr_preference table content:
+----+------+----------+--------+-----------+------+-------+---------------------+
| id | uuid | username | domain | attribute | type | value |
last_modified |
+----+------+----------+--------+-----------+------+-------+---------------------+
| 4 | | 1000 | | fork | 0 | 1001
| |
| 3 | | 1000 | | fork | 0 | 1005
| |
+----+------+----------+--------+-----------+------+-------+---------------------+
Kamailio correctly forks the call to 1001 and 1005, but the
Request-URI of the 1005 user is not correctly set, because the proxy
IP is used instead of the IP where the user is registered (10.1.2.15).
You can see the INVITEs below.
Could anybody tell me what I'm doing badly?
apart of first destination which is set in the r-uri, the rest become
branches. You have to loop back so they arrive as r-uri and location
lookup resolves the user address. lookup("location") works only with r-uri.
Cheers,
Daniel
Thanks for your time,
best regards
Anton
