I have a working Asterisk server with SIP trunks. Now I want to use my PSTN line also with it.
I read everywhere that this configuration needs a special voice card named XP100.
I know that it’s not too expensive but I have too many idle external modems at home. Is it possible to use external modems as FXO card ?
I read different opinions on this issue but I couldn’t understand it well.
If it’s not possible than I will go and buy a XP100 pci card.
Please help me.
