Systems and methods for selectively disallowing use of Media over Data in a network segment within a cellular network or a mobile communication network, at call initiation, in order to ensure a consummate user experience, are disclosed. An embodiment of the invention identifies a segment associated with a Media over Data call, at initiation, and utilizes a policy database to obtain a segment designation specific to the segment previously identified. Based on the segment designation, the Media over Data call is then either allowed or disallowed. The segment designation is based on segment conditions and/or subscriber policy characteristics.
