@virgiliomi:
No, you would need a special interface card that Asterisk would communicate with for the purpose of making/receiving phone calls on that line. There are two different kinds of ports that can be found on analog cards… FXO (line) and FXS (station). You want a card with FXO ports to be able to use the analog phone line. If you had analog phones that you were using through your Asterisk system, those would use FXS ports. FXS ports need to provide a bit of electrical power for the analog phones attached to them, while FXO ports don't.
By any chance are there any FXS port adaptors for USB that pfsense(or FreeBSD) recognizes properly OOB?

I have a modem it has a phone number ,etc…
You need to figure out how this voice part of your modem is configured. Generally there are 2 common options - this internal VoIP GW may use either Internet VLAN or it's own 'voice' VLAN. In the 1st case you will just need SIP credentials extracted from your modem, in a second - you will also need to bring your voice VLAN to pfSense and route it further to your Asterisk. Forget about the jacks ;)
Unfortunately the modem doesn't come with VoIP and it keeps it SIP gateway closed up although (The ISP doesn't actually provide VoIP directly but provides services using it, complicated stuff)
So ill have to go ask Jack if he's willing to phone PFsense.
