Can someone verify that these figures are correct?

According to this you should be able to route 11 G.729 calls using an
IAX2 trunk over a 128Kbps line.  It seems high, what sort of figures are
some of you getting?

The 30.0 kbps for a single call is about right. I don't use trunking, so
not sure about the remainder of those figures.

I would seriously doubt that you could get anywhere near 11 calls out
of a 128kb circuit (of any type).
