Asterisk server farm

Hi Everyone,

I’m working on a project which is to build an asterisk server farm with high availability and scalable.

I’ve looked at some online resources and here are them.

  1. opensips
  2. dundi
  3. kamailio
  4. sippy rtpproxy
  5. asterisk realtime architecture
  6. cloud instances

goals:

  1. To be able to automate the adding / removing of users depending on the number of calls.
  2. To be able to scale the number of asterisk servers depending on number of calls (dynamic asterisk servers).

What do you think is the best setup for that?
