Zfone SDK FLOSS License Exception
Under certain conditions defined on our Licensing Policy page, the Zfone SDK is available under the GNU Affero General Public License (AGPL), but is not currently available under a blanket FLOSS (Free/Libre/Open-Source Software) exception. However, if you need it for non-AGPL or non-GPL FLOSS applications, contact us anyway. We can probably work something out to meet your Open Source licensing needs.
