[Asterisk-Users] VSP? Looking for advice.

[Chris Shaw]

Also note that BV uses G.711A/U. It's the only codec they support. So you
need to have enough up and downstream bandwidth to support multiple calls
(About 80Kbit per stream depending on your sampling rate...) or it will
sound like absolute crap... QoS on your router or access device is almost a
requirement if you want good quality with ANY VSP...
