connection problem about dsl and dial up?

current set up:

Phone linephone faceplateasdl splittermodem 4 port router ethernet switchLan Pc’s
Note: Adsl splitterextention doubler, for 2 standard phone extention
—–Where”” connected to

First, I have VoIP phone, which best choice I’ve choose to connect ?
1.VoIP phone4 port router ?
or
2.VoIP phoneethernet switch?
Second, I have a another PC with fax modem installed since adsl connection does not support data fax. My question is where to connect my pc fax modem?
It is posible to connect my pc fax modem to extention doubler as my dial-up connection for data fax?
Third, Can I used my dsl line as dial up connection simultaneously for data ?
Or I need to subscribe another connection (dial-up)for my pc data fax?
