Design question


#1

What would I need if i’m NOT using VoIP.

The setup is 3-4 hardlines.
4-7 regular phones.

I can’t find an answer to these questions:
Do I need an FXO/FXS card for EACH of these lines? or some?

Also, if i have a regular phone, is it possible to have a voip adaptor, and use the internal network but still have the call leave via the hardline?

FXO connects to your telephone line or pots line
FXS connects to your telephone

Also, if i have a regular phone, is it possible to have a voip adaptor, and use the internal network but still have the call leave via the hardline

This is one of several different devices for that purpose
