Try to increase the verbosity in the log and see what happens.<br>You should be able to push more cps than 5, unless you have something wrong in you cfg, or your vendor limited your gw, etc.<br><br>-Laszlo<br><br><div class="gmail_quote">

<p class="MsoNormal">Using permissions to allow fixed gateway calls and sending them to another fixed gateway.</p><p class="MsoNormal">No registrations, no internal users just purely switching calls from one gateway to another.</p>
<p class="MsoNormal">I have accounting enabled but even if I switch this off it makes little difference.</p><p class="MsoNormal">I am using Sipp 3.2 with the send and receive instances on totally separate machines.</p><p class="MsoNormal">
All machines are dual core Pentiums with 4gig.</p><p class="MsoNormal">Opensips is running with –m 2048 and 16 child processes log 3 but this also doesn’t seem to effect the performance.</p><p class="MsoNormal">I have the rr module running.</p>
<p class="MsoNormal">Basically I run the sip processes at 1 call a second and slowly step up the rate (concurrent calls don’t seem to effect the performance).</p><p class="MsoNormal">4 calls a second is fine and I can leave it running like that indefinitely however soon as I go to 5 calls everything starts to fail with retransmissions everywhere.</p>
<p class="MsoNormal">Most of the invites seem to eventually get through but all the byes stop being processed.</p><p class="MsoNormal">Slowing the calls/sec down doesn’t seem to help, only pausing the transmission and waiting for everything to go quiet will allow me to begin again without restarting or resetting anything.</p>
<p class="MsoNormal">Blogs have people running these at silly call rates so getting above 5 shouldn’t be a problem.</p><p class="MsoNormal"> </p><p class="MsoNormal">Must be something basic that is wrong.</p><p class="MsoNormal">
</p><p class="MsoNormal">Any ideas?</p><p class="MsoNormal"> </p><p class="MsoNormal">Many thanks</p><p class="MsoNormal"> </p><font color="#888888"><p class="MsoNormal">Chris</p><p class="MsoNormal"> </p><p class="MsoNormal">
