When i lift the handset off the cradle the speaker light illuminates automatically, when I press the speaker button to disable it terminates the incoming call. Any ideas on how to disable this feature would be greatly appreciated.
I'm 99% sure its RMA time for these phones. This is most likely a problem with the Hookswitch. After deploying Cisco IP Phones for the last few years we (and many others) have found this to be the most common hardware problem.
There is a "Best Practice" for cleaning the Hookswitch contacts (link below) that does work on occasion. Usually the phone has to be replaced/RMA'd.

From this interesting Tech note;
There was also a problem with the 7.2 phone firmware that caused similar looking symptoms for the 3rd generation phones like the 7970/7961/7941. This could be rectified in the short term by booting the phone. If your issue can be fixed by resetting the phone and you are running 7.2 firmware, let me know and I will find you the Bug.
Hope this helps!
This isn't a feature, sounds like the phone is faulty more than anything. Does this happen on all the phones or just this one?
You can also go into the phone configuration in CallManager (use the MAC address or line extension to find it) and check the "disable speakerphone" option.
