[asterisk-users] Asterisk Manager API - Originate command

[Wai Wu]

Thanks for sharing your experience. I will play around with the Asteirsk
server tomorrow again. I took a look at it just before I left the
office. It has loads of crap. It's got all those non-essential things
and X windows running. Also, I can probably be able to get away with
starting a call every 30-50ms.

Thnx.

First off, you should be using Async: true

Secondly, you shouldn't really be doing 120 simultaneous calls.

If your server can take say 300 concurrent calls, you will probably need
to start those up with about 30ms between them.

If you really need to start 120 calls all at the identical time, you
probably want to be looking at clustering Asterisk servers.

In SmoothTorque we set a minimum value for delay between calls, then
have a funnel which accepts calls from predictive campaigns.

The funnel knows about the connections to the Asterisk servers, and
distributes the calls in a round robin fashion (assuming all servers are
up).

Each server has a queue which allows calls sent to that server to back
up, and if a queue gets too full calls won't be sent to that server.

If, after stopping the sending of calls to a server, the queue does not
empty out, the server is placed into an inactive state, and a server
marked as standby is moved into the active state.

Any calls which remain in the queue are redistributed to other servers.

Hope that helps!
