If I get a blank TDM400P card:
I have an internal VoIP network. I want to use NORMAL PSTN connection for all outside lines. I have 4 PSTN lines.
How many FX0 Modules will I need? 1? or 4?
refined: Will I need a module for each line? Or 1 module for all 4 if they will all have Same Exact Config???
4 FXO modules would do it…
