asterisk users - May 2005 - Problem developing my office

Hi all,
i need some advices. In my office we have 7 PSTN lines from central 
phone-office (one line - one number) and we plain to install an Asterisk 
server as PBX. We need to have 15 PSTN devices (phones, fax, etc) in opur 
office. I've seen FXS and FXO but i'm not sure: we need 7 FXO and 15 
FXS ?!?!?!?!?

There's a smarter solution ?

Thanks ! Oz

Yes, 1 per incoming line, as long as you plan to keep them all.

Theoretically, you need 1 FXS module per downstream PSTN phone you want to 
signal with Asterisk. Have you consider switching to VOIP (hard)phones, be 
IAX2 or SIP, since for those, you would not need any extra hardware at all ? 
Very good quality brands and models available (see Asterisk wiki).
