Stock dialer app on Andorid Kit Kat does not like to bring up the num pad
I had the same issue, not with Cyanogen, but stock android in Nexus 5 phone. I solved the issue temporarily as follows :

Go to Settings &gt; Developer Options

Change Animator Duration Scale to 0.5x (may be more. At first I set it in None, so it didn't work. Changing to 0.5x solved my problem. I didn't check other options like 1x etc).

This method solved me in Nexus 5. (Not sure about Note 2, try it and let's know)
