Risks of Spam over Internet Telephony

  1. Privacy invasion. SPIT poses a significant risk to user privacy by inundating individuals with unsolicited and potentially intrusive voice messages.
  2. Resource drain. SPIT consumes network resources and bandwidth, leading to network congestion and reduced service quality.
  3. Loss of productivity. SPIT disrupts users’ daily activities by bombarding them with unwanted calls and messages.

Protective tools against Spam over Internet Telephony

  1. SPIT Filters. They are software tools implemented by VoIP service providers to detect and block SPIT calls and messages. They analyze incoming traffic and assess various parameters, such as call frequency, caller reputation, and content analysis.
  2. Call authentication protocols. VoIP systems can employ call authentication protocols like Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS) to verify the legitimacy of incoming calls.
  3. Whitelisting and blacklisting. VoIP users can employ whitelisting and blacklisting features to control incoming calls. Whitelisting allows calls only from pre-approved contacts, while blacklisting blocks calls from specific numbers or sources.
