It actually does, but only very slow, like 2400 baud or so.
Worst case you can do 150baud which is like 2 frequency keying or something.

It’s not a lack of bandwidth that typically breaks dialup over VoIP, it’s the jitter.
The only potentially legitimate use for modems over (Vo)IP are faxes, and the proper way to do that is with T.38.
