It doesn't have to be "always on", just when you want to use it or take
calls - a bit like my girlfriends mobile.

It is possible to VOIP over an ISDN connection, but I never tried it. The
quality would probably be similar to PSTN, but not as good as raw ISDN.

It was possible to VOIP over dial up, but as you can imagine the quality
would be poor.

Perhaps someone can tell us if you can VOIP over 3G and how many channels
you need, bear in mind though that the network providers will intentionally
impede this working easily.
