Lync Call Popup to CRM entry

Hi everyone,

I would like to know if there's any free software that prompts Lync calls and provide the choice to enter or register the call as a case.

I found something similar but wasn't able to try it more than 5 mins as it's only available for demo version. I would appreciate if someone would point me to something similar.

Thanks
