Enhancing Security Protocol For Voip Communication Using Modified Vector Quantization

VoIP has introduced a new set of challenge that practically unheard off when a landline phone was used. Session Initiation Protocol (SIP) is often used as the main signaling protocol in VoIP. However, the lack of security feature has exposed SIP to a number of network threats. Public Key Infra...
