Systems and methods are disclosed for detecting the availability of common features (e.g. device functions and/or subscription plan features) associated with two or more communication devices, and indicating commonly supported features to at least one of the two communication devices. Disclosed systems can include components that can audit communication devices and communication networks to determine features supported by a communication, and components that can selectively mask unsupported features and/or reveal supported features.
