I can confirm this bug exist. But at the moment i have two asterisk with
the same binary, the same configuration files. On can reproduce the
problem, the other not.
I'm gonna try to understand the problem, give you a way to reproduce the
problem and the debug output.

I confirm also that using différent codecs "solves" the problem.
