kphone & Asterisk CVS HEAD: no audio

Next, I have kphone on the same Linux host, and VmWare virtual

kphone and stable 1.0.7 and 1.0.9 asterisk versions. Asterisk does
not claim that something wrong, it logs on its condole that it just

Solving Systems of Non-linear equations
I am trying to write a function that will solve a simple system of
nonlinear equations for the parameters that describe the beta
distribution (a,b) given the mean and variance.
mean = a/(a+b)
variance = (a*b)/(((a+b)^2) * (a+b+1))
Any help as to where to start would be welcome.

[nbdkit PATCH 1/9] server: Fewer dereferences in filter
Anywhere that we compute 'f = container_of(b)' then use 'f->backend.',
we can instead just use 'b->'. Similarly, during registration, we can
use the 'filename' input rather than our just-copied 'f->filename'.
