[cisco-voip] 7975G telephone features

[Robert Kulagowski]

According to 
http://www.cisco.com/en/US/products/hw/phones/ps379/products_qanda_item0900aecd80699b31.shtml

The 7975G features 8 line buttons and "KEM"

In the comparison table, it says that the 7970 and 7971 have 6 line 
keys.  I'm looking at the 7970 on my desk, and it sure looks like I've 
got 8 line keys.  What are they talking about?

What's "KEM"?

Also:  still no Bluetooth headset support?
