Get a T1/E1 card. They come in 4 port (TE4xxP series) and 1 port 
(TE110P) flavors.
You then connect each of those ports to a 24 FXO port channel bank.

So, to do the math, get a 4-port card and a 1-port card taking up only 2 
PCI slots.
You attach 5 24-port channel banks to them.
And no, you don't need to punch a gaping hole in your wall snaking 120 
phone lines into your office.

I'm sure there are better scenarios than this.
I just scaled up a setup I have.
