No,

Most VOIP uses compression which is pretty good. Most stay under 50kb/s, which is just a fraction of most users upload.

Actually, most don't; most VoIP providers use G.711, which is standard "uncompressed" PCM and uses ~90 kb/s on an IP network. Some (VoicePulse, most Asterisk-friendly providers, etc.) offer compressed codecs as an option, but only a few (namely P8) use compressed codecs by default.

G.711 ~90 kb/s
G.726-32 ~55 kb/s
G.729a ~32 kb/s
