Just a few questions. I’m planning on building an Asterisk FXO box. This is a small business with 10 analog lines running in the office. I’m pretty sure that would mean I’d need to get 10+ FXO modules, I’m looking at these, ( cigear.com/4-port-analog-pci … -1412.html ). My question, is this the only option I have if I want to use analog lines? I have the capability of changing all those analog lines into ethernet, but then purchasing phones for them all would be very expensive (I need to keep costs down). Any ideas?
