Abstract
A method for authenticating communication traffic includes receiving a Session Initiation Protocol (SIP) data packet sent over a network from a source address to a destination address, sending an outgoing SIP message to the source address, receiving an incoming SIP message in response to the outgoing SIP message and processing the incoming SIP response message so as to assess authenticity of the received SIP data packet.
