I have a Panasonic 46mhz portable phone that does the same.
It's a "Sound Charger Plus" with "10ch Secure Guard".  I think it
does a very simple analog operation to 'secure' voice transmissions.
Like someone else posted, it keeps Beavis and Butthead from
listening to your conversations, but that's about it.  I think
a dedicated ham, hardware-knowledgable hacker or Fed could do
a simple frequency-inversion or whatever and listen in.

This Panasonic cost about $80 from Frys.

You might get better security from one of the newer 900mhz digital phones.
Those would still be crackable but would require some digital
equipment, which is probably not yet as common.
