[PLUG] VoIP on DSL?

Jeme is correct. VoIP connections generally consume around 55kbps after
compression. (Both up and down, of course) So with an ADSL connection of,
say, 1500/256, you could easily have 4 VoIP "lines".

As to latency: most VoIP providers offer routers supporting QoS,
preconfigured to pre-empt VoIP traffic, ensuring the lowest possible
latency.

Why would VoIP require more bandwidth than a DS0 (64kbps)?  Hell, that's
not even hardly compressed.  Surely, latency is all that matters.
