Hi Iulian,<br>
<br>
Regarding your first issue, with the load:<br>
<br>
1) I suppose you do the lb stuff only for the initial request right ?<br>
<br>
2) you say you see the xlog() for all the received calls, so all received calls pass the lb function...but you do not see all calls being sent out, right ?<br>
<br>
<br>
Related to the second issue (with 2 logs for a single call), I suspect it may be a retransmission issue. To be sure, print in your xlog the callid also (to be sure it is the same request) . Var for callid is $ci.<br>
<br>
Regards,<br>
Bogdan<br>

Hello<br>
<br>
<br>
I have installed OpenSips 1.6.4 on CentOS 5.5 32bit with load balancing & mysql support ; I want to balance calls to 2 asterisk servers . I am sending traffic to opensips from 1 x gnudialer & 1 x vicidial ( so from predictive dialers ). Situation is like this:<br>
<br>
<br>
+----+----------+--------------------------+-----------+------------+-------------+<br>
| id | group_id | dst_uri | resources | probe_mode | description |<br>
+----+----------+--------------------------+-----------+------------+-------------+<br></div>
| 1 | 1 | sip:<a href="http://192.168.254.241:5060" target="_blank">192.168.254.241:5060</a> <<a href="http://192.168.254.241:5060" target="_blank">http://192.168.254.241:5060</a>> | pstn=300 | 0 | |<br>
| 2 | 1 | sip:<a href="http://192.168.254.242:5060" target="_blank">192.168.254.242:5060</a> <<a href="http://192.168.254.242:5060" target="_blank">http://192.168.254.242:5060</a>> | pstn=300 | 0 | |<div>
<div></div><div class="h5"><br>
+----+----------+--------------------------+-----------+------------+-------------+<br>
<br>
600 channels in total , and I send around 500 channels ; OpenSips drops a lot of calls; By drop I mean a call that is not sent to one of those 2 asterisk servers that I have.<br>
<br>
The code for balancing in this situation is:<br>
<br>
if (uri=~"^sip:0[1-9][0-9]*@") {<br>
load_balance("1","pstn");<br>
xlog("sending call $ru to $du\n");<br>
t_relay();<br>
exit;<br>
}<br>
<br>
! An important thing to say is that in /var/log/messages I see the specific number that is sent to 192.168.254.241 for example ; So the parameter xlog("sending call $ru to $du\n"); works ; The problem is that in logs on 192.168.254.241 that number never arrives in asterisk logs ; In logs of vicidial & gnudialer I see it like congestion.<br>
<br>
If I do something like this:<br>
<br>
+----+----------+---------------------+-----------+------------+-------------+<br>
| id | group_id | dst_uri | resources | probe_mode | description |<br>
+----+----------+---------------------+-----------+------------+-------------+<br>
| 1 | 1 | sip:192.168.254.241 | pstn=150 | 0 | |<br>
| 2 | 2 | sip:192.168.254.241 | pstn=150 | 0 | |<br>
| 3 | 1 | sip:192.168.254.242 | pstn=150 | 0 | |<br>
| 4 | 2 | sip:192.168.254.242 | pstn=150 | 0 | |<br>
<br>
And I split opensips balancing in 2<br>
<br>
<br>
if(src_ip==192.168.3.10 )<br>
{<br>
load_balance("1","pstn");<br>
xlog("sending call to $du\n");<br>
t_relay();<br>
exit;<br>
};<br>
<br>
if(src_ip==192.168.3.11 )<br>
{<br>
load_balance("2","pstn");<br>
xlog("sending call to $du\n");<br>
t_relay();<br>
exit;<br>
};<br>
<br>
<br>
and by doing this I get the same numbers of channels on opensips ( around 500 channels ) but I am splitting in 2 groups of load balancing; It can process all the calls.<br>
<br>
Another question that I saw is that when I make a single call to opensips and I involve load balancing in /var/log/messages I get 2 times the same message .. just like it send 2 time to asterisk server the call .. but on asterisk I receive only one time.<br>

<br>
<br>
Isn't load balancing fast enough the process the calls made by predictive dialers, when over 300 channels is sent .. ? Or I have some mistakes made .<br>
