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?
