<div><br></div><div>The mistake was very minor as in the load_balancer table I was giving group id as 1 to all the destination servers while in dispatcher table the group id was same for the three servers as 1 but different for the two servers as 0 & 2, so that was the reason there were no calls on these two servers & was fixed assigning the same group id as 1 to all the servers & the calls were distributed equally after the second load test :)</div>
<div><br></div><div>Ntop is I think for network monitoring & I installed it on one of my servers but don't know the exact mechanism of its monitoring for SIP especially. I am only dealing here with SIP yet so there isn't any built in tool or command in OpenSIPS for packet loss

<div>Hi,<div><br><div>Really nice to see your issue is resolved, mind sharing the mistake you had in table !?</div><div><br></div><div> About the packet loss, try using some traffic monitoring tool for this like ntop, or some snmp based interface monitoring utility to find packet loss. If you are talking about call Media packet losses then you can get the stats if you're using RTPproxy. Rtpproxy publishes media stats at the end of the call.</div>

<div><span><br></span></div><div><span>The issue is fixed & it was due to my mistake because I was using some different values in the dispatcher table. By the way I have got one more question which is that how can I check the total packet loss in OpenSISP for the whole traffic?</span></div>

<div>Hi Faisal,<div><br></div><div>Please share the contents of load_balancer table. I doubt that the group defined (or as Vlad doubt resource assigned)for the servers are different thats why they are not receiving the traffic.<br>

Hello,<br>
<br>
If using the load_balancer module, do the two servers that get no
traffic at all have the same assigned resources as the other 3
server that get even distribution of calls ?<br>
<br>

<div><span>I was testing my OpenSIPS loadbalancer in live

surprised to see that there were two servers where there was
