If you really need G729 support you should look at either getting the proper licensing from freeswitch.org or look at other hardware options available.<BR>

This is to protect the project in general and the livelihoods of the dev team.<BR>

<BR>
We have been playing with Intel IPP G729 code and its module for FreeSWITCH. <BR>
<BR>
As reported here, we have successfully compile the fs-g729 module after install IPP libraries. <BR>
<a href="https://code.google.com/p/fs-g729/issues/detail?id=3#c1">https://code.google.com/p/fs-g729/issues/detail?id=3#c1</a><BR>
<BR>
However, to test the codec in a loopback SIP call (FreeSWITCH calling itself over SIP), I need some G729 encoded files (do I really?)<BR>
<BR>
FreeSWITCH gives errors with G729 encoded file from here <a href="http://www.enicomms.com/cutglassivr/audiofiles/Alison_Keenan-British-English-g729.tar.gz">http://www.enicomms.com/cutglassivr/audiofiles/Alison_Keenan-British-English-g729.tar.gz</a><BR>
Dialplan<BR>
<action function="play-file" data="ivr/demo-thanks.g729"/><BR>
<BR>
[ERR] switch_core_file.c:122 Invalid file format [g729] for [/usr/local/freeswitch/sounds/en/us/callie/ivr/demo-thanks.g729]!<BR>
<BR>
And also gives errors with file encoded using Intel IPP sample G729 encoder. <BR>
<action function="play-file" data="ivr/ivr-welcome_to_freeswitch.g729"/><BR>
[ERR] switch_core_file.c:122 Invalid file format [g729] for [/usr/local/freeswitch/sounds/en/us/callie/ivr/ivr-welcome_to_freeswitch.g729]!<BR>
<BR>
Please note that the files are actually kept in the directory /usr/local/freeswitch/sounds/en/us/callie/ivr/8000 as are other demo_ivr sound files. <BR>
<BR>
# file /usr/local/freeswitch/sounds/en/us/callie//ivr/8000/*.g72*<BR>
/usr/local/freeswitch/sounds/en/us/callie//ivr/8000/demo-thanks.g729: data<BR>
/usr/local/freeswitch/sounds/en/us/callie//ivr/8000/ivr-welcome_to_freeswitch.g729: RIFF (little-endian) data, WAVE audio, mono 8000 Hz<BR>
<BR>
I suspect that ivr-welcome_to_freeswitch.g729 (produced by Intel IPP G729 encoder) is not really G729. <BR>
<BR>
Any pointers will be most helpful.<BR>
<BR>
Thanks!<BR>
Anita. <BR>
