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?
Thanks for your time,
best regards
Anton
