Analog phone networks are actually digital networks with analog "ends".

The links between pretty much everything is digital, save the link from
your CO to you.

So, if both you and the number you are calling have an analog "end",
i.e. you have an analog link to your CO and they have an analog link to
their CO, then V34 (33.6k ideally) is the most you're going to get.

If OTOH the number you are calling is connected digitally to their CO
then your modem can take advantage of V90/V92 and get up to 53.3K (in
NA) down.
