The codec Skype uses marginally fits within the bandwidth of a modem
connection. Likewise will speex.
Modem connections also have a relatively high latency. I seem to recal
that the hop of a modem has a delay of some 100ms. This is something you
might even notice. But latency isn't that a problem with VoIP
connections.
A worse problem with VoIP, that tends to accompany latency, is jitter:
how much different packets have different time. An ideal VoIP stream
would have the exact latency and thus no cracks.
