[Freeswitch-users] Open g729 g723 codec, any expierence

My company wrote a g729/g723 codec for CallWeaver last year completely
independently of the Readytechnology codec.  It is fully functional but was
never publicly announced (although is publicly available) due to discussion
on CallWeaver lists indicating it probably wouldn't be accepted.

We purchased a redist license for the Intel libraries and verified with
Intel that said libraries could be redistributed free as in beer.  

Overview

  This software provides G.729 and G.723.1 codecs for Callweaver based on
  version 5.1 of the Integrated Performance Primitives library provided by
  Intel. The codecs are implemented as a thin wrapper around Intel's Unified
  Speech Codec Interface (USC) sample for IPP. This allows codecs exposed by
  the USC interface to be easily adapted for use by Callweaver.

The Makefile allows for either static or dynamic linking to the appropriate
IPP libraries at run time to handle different architectures without
recompiling.

The code can be found at http://www.zettaserve.com/default.asp?catid=78 and
if anyone wants to adapt it for use with FreeSwitch please feel free.  I am
not a coder and so have no idea how hard or easy it may be to adapt for use
by FreeSwitch, however I do know that our codec is much easier to compile
than the Readytechnology codec.  It was developed and tested on OpenBSD 4.0
and is known to work on Linux.  Of course the user is responsible for any
applicable codec licensing.  We do not provide binaries.
