  Well, to be clear, the IPP code does not dump core.  g729 works
well.  I made g729 the first code, and ulaw the second option in
Asterisk.  But If I change the config of an UA to use ulaw first,
Asterisk core dumps.

  So, the IPP driver can be used, but it better be the only CODEC you
accept, otherwise Asteriks crashes.

  I also think the IPP driver is an universal g729 driver.  That is,
it can handle any g729 variant.  In fact, how do you select different
g729 variants in allow= statements, if there are different drivers for
each variant?

  I plan to try the HEAD branch.  The 1.0.x branches aren't that
stable.  1.0.6 was put out even though something basic like MOH
doesn't work.  Every other stable release seems to have a major flaw
in it.
