It would have to.  Up to 1200 baud (202/212) didn't use any compression at
all, and was pure audio FSK.
Once you hit 2400 baud the 'training' cycle came into being, that noisy
connection-establishment phase
that is so characteristic of dial-up in the public psyche, and that's I'm
sure what runs afoul of VOIP.

In spite of faster modem standards, credit-card readers that used dial-up
stuck with 300/1200 baud
simply because there was no training time required, and the amount of data
needed was so small
that the time to make the connection and get the data was least when using
the oldest slow standards.

I've been listening to some vintage computer podcasts that have talked about 
the issues trying to use a modem over today's VOIP phones. Apparently the 
compression used today prevents modem use. There is a theory that 300 baud 
would be slow enough that it's still work...
