[Freeswitch-users] Using a dial-up modem to connect ordinary phones

Hi there I am quite new to FreeSWITCH and VoIP. I have been searching the net and the users-list archive, but can't seem to be able to find an answer to this question: Can I use an old fashion dialup modem to connect an ordinary phone and hook to VoIP? Any pointers, references appreciated. Thanks in advance. -z
