In order to better align Phono with our overall offering, we are removing public access to the project as of 12/22/2015. It will be back, and with more functionality integrated into both Tropo and other Cisco products. Please watch both the Tropo and DevNet blogs for more information on the release of the new and improved Phono, and email if you have any questions. If you want to learn more about our Products & APIs, please check out using the menu items above and Cisco Spark for Developers.
