That can help and probably plays more a factor in professional deployments
but for the hobbyist using the common broadband transports (cable, xDSL,
...) I find it mostly comes down to just getting the quickest connection
you can reasonably afford and cranking up the jitter buffer :O

Just using G.711 u-law (I haven't really played with other codecs to say
whether that could be a factor) end-to-end I've been able to achieve 28.8
kbps+ connects over VoIP with 50/10 Comast "business" as the transport on
my side.
