Is it possible to extend Lync incoming call popup?

Currently I'm seeing only phone number of the caller. Is it possible to extend incoming call popup(add additional information querying DB by phone number) ?

I'm using Lync SDK 2010.

Thanks in advance

As far as I know this is not possilbe.

You can instead hook into the Lync client using the SDK, catch the incoming call event, and display a second popup with your own data. Some styling and positioning would make it near perfect.
