Spreading * servers across multiple floors sounds like a bad idea since
it'd increase maintenance time. With your projected call volume there's
no way you can reliably run g729 or any other CPU hog of a codec on a
single box. For this kind of a setup you'd need 2-3 boxes and a
SER/heartbeat box to handle registration and call distribution. I would
also isolate CDR recording to a separate box running a database like
Postgres (IMHO better choice due to WAL) or MySQL.<br>

<br>><br>><br>><br>Yes, leaving H323 out of the story is a good way to start the project :)<br><br>_______________________________________________<br>--Bandwidth and Colocation provided by <a href="http://Easynews.com">
