RingRx provides enhanced security on its products and services to ensure patient information is adequately protected. One security measure available in the mobile app is (SDES Session Description Protocol Security Descriptions), which is a method of securing media transmissions. All calls initiated on the mobile app are protected with this additional layer of audio security.
On the mobile app, some calls may display a security icon in the form of a lock indicating the transmission is secured with SDES
