Note that it's not just the build system that we're patching heavily:
we're also patching Asterisk's dynamic loader to avoid a dlclose() on
the library that results on a segfault. Upstream "handles" that by
linking the main asterisk binary with libopenh323 (instead of just
chan_h323.so) therefore making it to never unload. That didn't work out
for us, of course.

This was a hell to debug and workaround; the dlclose() segfault was
reported to openh323 years ago and nobody ever reacted. More @
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=438815

That said, I'm afraid that chan_ooh323 is nowhere towards feature parity
nor stability wrt to chan_h323… Or at least that was the case last time
I cared.
