Default iLBC codec legal status

Hello All!
ILBC is a low-bitrate codec used in many OSS and commerciall
applications. However its legal status isn't clear at least for me.

Codec itself distributed in opensource form, but no publically
available tarball available exists. Instead of this, sources of
reference implementation can be accessed as an appendix to RFC 3951:

http://www.ietf.org/rfc/rfc3951.txt

Someone already extracted source from this RFC, and extracted sources
available as 3rd party library in many OSS voip projects, for example:

http://download.savannah.nongnu.org/releases/linphone/1.3.x/source/ilbc-rfc3951.tar.gz

The source has no explicit license but every file in tarball contains
the following header:

=================================
/************************************************** ****************

iLBC Speech Coder ANSI-C Source Code

iLBC_encode.h

Copyright (C) The Internet Society (2004).

At the iLBC site ( http://ilbcfreeware.org/ ) they mention that this
codec is FREE (meaning that no fee required), but under the following
license:

accessing the Original Code You agree to the License terms. PLEASE SEE
THE COMPLETE LICENSE BELOW FOR
ADDITIONAL TERMS. In general:
- Personal, non-commercial use is generally permitted.
- Commercialization is permitted with certain limitations; for
example, to ensure that every iLBC decoder can decode
every iLBC-encoded payload, commercial "Deployment" must comply
with the applicable IETF Standard/draft, and the
format of the bitstream may not be modified.
- You are provided no warranty or support, and all liability is disclaimed.
- You must register this license with GIPS prior to any commercial
Deployment.

=======================

Is it acceptable for inclusion into Fedora? If yes, then what sort of
license is this?
