Are Leitner Wireless Headsets PCI Compliant?

Technically Leitner wireless headsets are not PCI compliant.  What it does include is the following:

• Registration procedure and time limits set to 120 seconds or less
• On-air 64 bit authentication key allocation (Base & Headset)
• Authentication of Base & headset
• Evaluation of peer sides behavior regarding encryption including timeout values for triggering of call release
• Early encryption immediately after connection establishment between headset and base established
• Procedure for re-keying with a new derived cipher key during a call so that cipher key can be changed at least every 60 seconds during a call

Ultimately if that level of security does not meet your needs your would need to go with a wired headset option to remove the need for wireless encryption/security. We do not have information on wireless headsets that are up to that level of security.
