VoIP Encryption

If you currently use a Stanford desk Voice over Internet Protocol (VoIP ) phone to collect or confirm credit/debit card information and process the payment or refund through any of the following payment methods, the desk phone must be encrypted per PCI DSS Compliance Policy #29.1.

Payment methods:

  • A Point-of-Sale (POS) credit card terminal
  • A PCI workstation and a payment gateway virtual terminal (e.g. CyberSource VT)
  • A PCI Point-to-Point Encryption (P2PE) key pad

Once the desk phone is encrypted, an after-business hours process will "reboot" the equipment in order to activate it. Please follow the below instructions to request VoIP encryption. Due to the volume of requests, please allow 4 - 6 weeks lead time to complete the encryption after your initial request. Please submit your request by 9/30 so that the VoIP encryption can be completed by the annual PCI DSS compliance deadline that will take place in the October ~ November timeframe.
