1. A method for enabling network based media manipulation in a communication network, comprising:
- receiving call setup signaling messages from a first endpoint device and a second endpoint device during a call setup of a call;
capturing by a call control element media handling capability information of the first endpoint device from a first session description header of the call setup signaling messages; and
capturing by the call control element media handling capability information of the second endpoint device from a second session description header of the call setup signaling messages, wherein the media handling capability information comprises a codec standard.

Abstract
The present invention enables the network to provide enhanced processing of the media stream before and/or during the call establishment. In one embodiment, the network can use the Session Description Header information to provide service support such as mid call Dual Tone Multiple Frequency (DTMF) detection, transcoding, and media conversion within the network instead of between two intelligent endpoint devices.
