[asterisk-users] How to combine a Fritz ISDN card with analogue handsets

[Frank Church]

I want to use a Fritz AVM ISDN card to create a switch which is
connected to 4 analogue extensions.

I believe I need a 4 port FXS module for that, are there any cheap but
reliable options out there?

Are there some guides that go through the whole process?
