Steganography and Steganalysis in Voice over IP: A Review [PDF]
The rapid advance and popularization of VoIP (Voice over IP) has also brought security issues. VoIP-based secure voice communication has two sides: first, for legitimate users, the secret voice can be embedded in the carrier and transmitted safely in the

Assessment of voice over IP as a solution for voice over ADSL [PDF]
The paper compares VoATM and VoIP in terms of their suitability for carrying voice traffic over DSL. ATM is currently the preferred protocol due to its built-in QoS mechanisms. Through simulations, we show that IP QoS mechanisms can also be used to achieve comparable performance for voice traffic over DSL.
