Call Spoofing

Proactively Detect Call Spoofing Attacks with Sophisticated Algorithms from RedShift Networks


Call Spoofing attacks change the Automatic Number Identification (ANI) on an inbound call to originate from an unintended source. This makes traditional security detection difficult and blocking nearly impossible. Call Spoofing is usually a precursor to more targeted attacks such as Phishing, TDoS, Voicemail theft, Toll Frauds, or financial fraud.

The advent of VoIP and use of SIP within 5G VoLTE networks simplifies attacks for perpetrators and fraudsters. The create a spoofing incident to flood enterprises and contact centers with illegitimate spoofed calls disrupting normal business.

Outcomes are typically negative including:

  • Customer, partner, prospect traffic grinds to a halt
  • Customer dissatisfaction and churn
  • Enterprise and/or service provider loss in revenues.


Simple 1-touch call authentication technologies as a brute force first preventive measure are industry standard. These can work but require user intervention with additional workflow steps and inconvenience.

RedShift Networks provides sophisticated algorithms (patent approved) to proactively check for Caller ID spoofing attacks. This approach provides deep UC aware stateful inspection checks that identify SIP anomalies at various layers using combination of:
