I just said goodbye to ATT and ported my home number over to VoIP. What I want to do is keep everything sip in my basement and wire my existing punchdown block to my asterisk box and connect my existing analog phones in my house to asterisk. My question is this would 1 FXS port on a digium card be sufficient? or would i need a FXS port for each phone that I want to connect. Because I would like to keep everything as it was before. 1 call at a time on the analog phones would be fine.
