For your first question would this work?

<br />For your second question I hear that SEMS has better performance than Asterisk or Freeswitch, but I think you have to put a lot of work into it because it isn't as easy to work with as Asterisk.

<br />If you can't figure SEMS out then maybe your best bet for an IVR that can handle 1000 calls would be Asterisk Clustering.
