Hi, Does anyone know what the license is of libzrtp for usage with FreeSWITCH? In the FreeSWITCH source I see a file docs/zrtp_agpl-3.0.txt but the libzrtp source itself is not included. So I got libzrtp-0.81.514 and in the source there is a file zrtp_legal.c that says: * libZRTP SDK library, implements the ZRTP secure VoIP protocol. * Copyright (c) 2006-2009 Philip R. Zimmermann. All rights reserved. * * The version of the SDK library that is packaged with this legal notice is * NOT licensed under the GPL, AGPL, LGPL, or any other open source license. * For licensing terms or other information, * contact Philip R. Zimmermann <prz@mit.edu>. * For more contact information, see http://philzimmermann.com * * This file must be packaged together with the rest of the libZRTP SDK * source code. That's why it's in a .c file. * * This software may be subject to export controls by the US Commerce * Department's Bureau of Industry and Security. This software is provided * "as is," with no warranty expressed or implied. This is quite the opposite of what zrtp_agpl-3.0.txt suggests in the FreeSWITCH source. Any ideas? Regards, Patrick
