What are you trying to do? Are you getting DSL or Cable with VOIP?
If DSL, the signal comes over the regular phone line to a DSL modem. From there you connect CAT5 to either your computer or a router. There are usually 2 or 3 connectors on a DSL modem, a modular phone jack, an ethernet connection, and sometimes a USB port. In this case you don't "have" to do anything to the existing wiring but you will need to put "filters" at each phone jack.
If Cable with VOIP, the signal comes over RG-6 to a Cable Modem. It will have a modular phone jack on it but it's an "output." You need to disconnect your existing phone jacks from the NID (telco box) and then you can plug it in anywhere and it will feed your regular phones. It will also have an ethernet port for your computer or router.
Saying all this, I'm with Jim. Run new cables. Even though DSL should work, you'd have reduced interference and possibly higher speeds with Cat5.
