Hi Diego,
The bug seams to be in your callee device. Take a look at the 200 OK it
sends:
U 192.168.2.165:5061 -> 192.168.2.165:5060
SIP/2.0 200 OK..From: "Your Long

The 200 OK is sent from 192.168.2.165:5061, but in contact it places
sip:[email protected] -> the port is missing, so the sequential
requests are going to the wrong destination (to
sip:[email protected] which is actually the LB ,not the callee)

Have you been able to take a look at the traces I sent?

Subject: [OpenSIPS-Users] Problem with load balancer module
Hi Bogdan,
Thank you for your prompt response. I'm sorry I couldn't send the trace
before but I had some problems with my network.
Also I've change the IP Address schema.
The call is originated from 192.168.2.150 to 192.168.2.165:5060 which is the
opensips address. Currently, the load balancer is configured to redirect the
calls to 192.168.2.165:5061 or 192.168.2.165:5062. In the call I'm sending
the INVITE was redirected to 5061.
The you will see that the ACK is not redirected to the destination.
Thanks
Diego

Hi Diego,
Could you post a SIP capture of a complete call (starting with INVITE) from
the opensips LB machine ?

Bogdan

Subject: Problem with load balancer module
Hello,
I’m testing the Load Balancing module and I have a problem I can’t fix
by myself. The INVITE message is routed correctly to one of the
destinations.
However the subsequent ACK and the BYE messages are not sent to the
destinations.
I set up opensips to run only in the udp 5060 port. Then I have two
identical applications: one running on port 5061 and the other on port
5062, the 3 components are running in the same server which has a
single IP
address: 192.168.1.195.
The application is very simple:
1. Receives the INVITE, starts streaming the RTP, and sends the OK
2. When the ACK is received injects some music in the streaming
3. Waits until de BYE is received. Then stops the streaming and
sends
the OK.
This is the configuration of the load_balancer table:
mysql> select * from load_balancer;
+----+----------+------------------------+-----------+------------+---
+----+----------+------------------------+-----------+------------+---
+----+----------+------------------------+-----------+------------+---
----+
| id | group_id | dst_uri | resources | probe_mode |
description |
+----+----------+------------------------+-----------+------------+---
+----+----------+------------------------+-----------+------------+---
+----+----------+------------------------+-----------+------------+---
----+
| 1 | 0 | sip:192.168.1.195:5061 | pstn=1 | 0 |
|
| 2 | 0 | sip:192.168.1.195:5062 | pstn=1 | 0 |
|
+----+----------+------------------------+-----------+------------+---
+----+----------+------------------------+-----------+------------+---
+----+----------+------------------------+-----------+------------+---
----+
I've configured only one resource in each application because I'm just
testing.
Finally, this is the configuration script, which is the one from the
tutorial on the website:
debug=3
log_facility=LOG_LOCAL6
fork=yes
children=4
/* uncomment the following lines to enable debugging */
debug=6
fork=no
#log_stderror=yes
/* uncomment the next line to disable TCP (default on) */
disable_tcp=yes
port=5060
/* uncomment and configure the following line if you want opensips to
bind on a specific interface/port/proto (default bind on all
available) */ listen=udp:192.168.1.195:5060

exit;
}
if (!has_totag()) {
xlog("[Redmond] Hast'n to tag\n");
# initial request
record_route();
} else {
# sequential request -> obey Route indication
xlog("[Redmond] Has to tag\n");
loose_route();
t_relay();
exit;
}
# handle cancel and re-transmissions
if ( is_method("CANCEL") ) {
if ( t_check_trans() )
t_relay();
exit;
}
# from now on we have only the initial requests
if (!is_method("INVITE")) {
xlog("[Redmond] Not invite\n");
if ( t_check_trans() )
t_relay();
exit;
#send_reply("405","Method Not Allowed");
#exit;
}
load_balance("0","pstn");
# LB function returns negative if no suitable destination (for
requested resources) is found,
# or if all destinations are full
if ($retcode<0) {
xlog("[Redmond] Service full\n");
sl_send_reply("500","Service full");
exit;
}
xlog("[Redmond] Selected destination is: $du\n");
# send it out
if (!t_relay()) {
sl_reply_error();
}
}
It seems that the route is not saved, because the To tag is sent in
the ACK and BYE messages, also the logs I've added are written as
expected for each message. If necesarry I can send a new email with
the
log attached.
Please, can you help me to find what's wrong?
Thanks
Diego
