asterisk users - Apr 2003 - bandwith calculation

I would like to know how to calculate the amount of bandwith I would need to
host X number of calls.

For example, if user A in San Francisco with an ATA 186 calls user B in New York
with an ATA 186 and Asterisk is being hosted in a PC in Miami. How much bandwith
do I need to have in Miami?  Do I just need bandwith for the setup of the call
(ie the SIP part) or are there any instances where the RTP stream goes through
Miami as well?
