[Asterisk-Users] Digium Hardware Question from Newbie

[Jeff Borders]

Hello folks,

I'm very interested in the Digium/Asterisk combination but need some
clarification.  I would like to setup a SOHO for business and home use.

Scenario One:
I have one analog line, 4 analog telephones.  
Do I need a TDM400P + 4 FXS modules (Green) + X100P?

Scenario Two:
2 analog lines, 1 selective ring number for fax, 8 analog phones.

Is this what I need?
2 TDM400Ps and 8 FXS for 8 phones
2 X100Ps for 2 lines
or maybe:
3 TDM400Ps and 8 FXS and two FX0 modules (Red)

Thank you,
Jeff Borders
