1) No. Because every case is a bit different and nobody has taken the time 
to research and document it.

2) In the 'hundreds.' I have a 5 yr old 3.4 Xeon server with 2GB of ram 
running all kinds of AGIs that handles 300 simultaneous ULAW calls without 
issue and without any 'tuning.' The Asterisk process uses less than 100MB
so more GBs means nothing.

3) Probably in the thousands depending on what those calls are doing. 
(Just guessing here because I have no experience with this configuration.)

Would a SIP server like OpenSIPS be a better platform choice?

More details will yield better responses.
