How can one listen in on cordless telephone conversations?

[Tonto]

Dect 6.0 telephones are becoming more popular. It was once relatively easy to listen to telephone conversations with police scanners, but it's thought by many to be almost impossible to do with the cordless telephones of today.

But today I found this:

Anyone know how to pull this off?

that article discussed cracking of DECT in germany (1.8Ghz) not DECT 6.0 used in the US (1.9Ghz)

not sure if that makes too much of a difference... but very curious to know if anyone else on here has any further information regarding this.

If you can find the proper card you can indeed listen in to DECT. https://dedected.org/trac

The Com-On-Air card that most use for this is no longer made, and thus a tad rare. The next possible solution seems to be the USRP which can listen in to this stuff along with Linux, but it costs $700

You can find all the info on the above page.

You can get USRP devices at http://www.ettus.com/products or you check out the schematics - http://gnuradio.org/redmine/wiki/1/USRP

My first though was, "what about the encyption?".  Then I learned it can deactivate the encryption by pretending to be a base station.  Interesting stuff....
