Techniques for identifying media network flows that use dynamic codec identifications are described. In an embodiment, network flow information for a network flow between a first endpoint and a second endpoint is received from a network device interposed between the first endpoint and the second endpoint, wherein the network flow information includes at least an address for the first endpoint and a particular payload identification number. A request is sent to the first endpoint for one or more characteristics belonging to the first endpoint. In response to receiving the one or more characteristics, a profile database is searched for an entry that maps the one or more characteristics to a profile, wherein the profile maps one or more payload identification numbers to one or more encoding types. An encoding type for content transferred over the network flow is determined based on the profile and the particular payload identification number.
