So it is a hardware issue and not software?<br>
I am afraid that asterisk software it self is not able to support 20 000 users and 2000 concurrent calls.<br>
<br>
About the high availability: is there a method that if the first asterisk server down, then the call will stay connected and failover to second asterisk server?<br>
<br>
