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>
| 1 | 1 | sip:<a href="http://192.168.254.241:5060">192.168.254.241:5060</a> | pstn=300 | 0 | |<br>| 2 | 1 | sip:<a href="http://192.168.254.242:5060">192.168.254.242:5060</a> | pstn=300 | 0 | |<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>Mar 10 14:58:47 opensips /usr/local/sbin/opensips[27611]: sending call to sip:192.168.254.241<br>Mar 10 14:58:47 opensips /usr/local/sbin/opensips[27611]: sending call to sip:192.168.254.241<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>
