<p class="MsoNormal">We got NORMAL_CIRCUIT_CONGESTION error trying to perform 100 simultaneous calls, and only 40 simultaneous calls actually happen (all other fail with NORMAL_CIRCUIT_CONGESTION). We have 1gbit/s network, all default rtp ports are open, and
<a href="http://switch.conf" target="_blank">switch.conf</a>.xml sessions-per-second=1000 (most freeswitch and gateway configs are default). We run dedicated server. Provider tell that 500 lines are available. Is it possible that I missed some config that could
 limit gateway channels, or this is definitely provider issue?<u></u><u></u></p>
