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.
Best,

It's all about latency and jitter. If you can keep the latency and jitter

the link is very bad, good luck, even at 300 baud.
Is this something usually made better by setting up QoS or traffic shaping?
