VoIP bandwidth requirements

[rsamuel708]

Are there any formulas anyone uses for determining WAN circuits for locations that will be utilizing VoIP. We currently always request 100mb circuits if the circuit will have ip phones, but I'd like a way to determine the "right" sized circuit.

Thanks in advance.
