Embodiments of the invention provide systems and methods for controlling a media session. According to one embodiment, a method for controlling a communication session can comprise receiving a request to perform a call control function from an application via a northbound interface of a call control enabler. The northbound interface can provide an abstract interface for invoking one or more of a plurality of call control functions. The call control function can be requested from a first network resource via a southbound interface of the call control enabler specific to the first network resource. In some cases, results of the call control function can be received from the first network resource via the southbound interface of the call control enabler. The results of the call control function can then be returned to the application via the northbound interface of the call control enabler.
