Embodiments disclose a method that may be used for diagnosing, for example, Voice over Internet Protocol (VoIP) sessions. The method may include establishing a first streaming session between a first telephone and a server using session control messages and establishing a second streaming session between the first telephone and a second telephone using session control messages. The method may further include transmitting or receiving data packets using the second streaming session, wherein the data packets carry voice or video data between the first and second telephones. The method may further include echoing the session control messages used to establish the second streaming session or the data packets carrying the voice or video data to the server using the first streaming session.
