When two standards development authorities, in this case the IETF and the 
ITU share text, each is entitled to publish as it sees fit.  The ITU have 
a "non-free" copyright statement: 

 Access to databases of the International Telecommunication Union (ITU) 
 for consultation of documents and/or information retrieval is permitted by 
 the ITU subject to the user's acceptance of ITU's provisions and conditions 
 of copyright contained within each document which obliges the user not to 
 duplicate the document or parts thereof for distribution or sale external 
 to the user's organization...

but the IETF have a "free" copyright policy, and RFC 3015 
http://www.ietf.org/rfc/rfc3015.txt contains the statement:

Cuervo, et al.              Standards Track                   [Page 178]
RFC 3015              Megaco Protocol Version 1.0          November 2000

   document itself may not be modified in any way, such as by removing
   the copyright notice or references to the Internet Society or other

   developing Internet standards in which case the procedures for
   copyrights defined in the Internet Standards process must be
   followed, or as required to translate it into languages other than
   English.

   The limited permissions granted above are perpetual and will not be
   revoked by the Internet Society or its successors or assigns.

It seems to me that if a packager takes file rfc3015.txt from the IETF, 
its "free", and may be redistributed.
