[asterisk-ha-clustering] Queue clustering

[Leandro Caetano Gonçalves Lustosa]

I found many names: heartbeat, csync2, DRBD, Ultramonkey, etc....
But I haven't found I way so far....

First of all, I thing we should state the requirements of a HA and
scalable Asterisk infrastructure:

1) Active call center:

- Many Asterisk servers with E1 cards. Or many Asterisk servers connected to
media gateways able to complete calls to PSTN;
- Many operators logged on theses servers making calls;
- A simple DNS configuration to load balance;
- If a server crashes, the softphone should re-log the operator in another
server;
- If a Media gateways crashes, the asterisk should use another media gateway
to complete calls;
- I think that realtime configuration is needed. But what is needed to have
a HA mysql DB?????

2) Receptive call center:

Many Asterisk servers with E1 cards. Or many Asterisk servers connected to
media gateways able to receive calls from PSTN;
- Many operators logged on theses servers receiving calls;
 - If a server crashes, the softphone should re-log the operator in another
server and the media gateway starts to send calls to another server;
-> How could we have a unique queue?????
