ok. So, with this in mind, if I was to acquire that 24 ports, 1 FXO
modules, the rest FSX modules. I could have 1 public telephone number to
the PSTN (3 wasted for this example), 20 analog phones inside the
company's branch, each phone having its extension in Asterisk? Or could
I have just the smaller card allowing me 1 FSO and 3 FSX and some kind
of "hub" to connect some number of analog phones (let's say 20)? If so,
does the number of FXS limit the number of my simultaneous telephone
calls?

Sorry for the dumb questions, but your answers are highly appreciated.
