[Freeswitch-users] g729 sound format for Intel IPP codecs

[Ken Rice]

The IPP Codecs are NOT supported by the project. These are not useable in
any production environment where the core developers reside due to Patent
and other IP Law restrictions.

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.

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