Send an email to contact when new note is added/updated?

I am working on functionality where I need to send an email to contact in the case when a new note is added OR existing note is updated and case origin is “Phone”

I have checked the workflow module but it sends an email to a specific email id only and not to the contact of that case.

I have also checked
/modules/AOP_Case_Updates/CaseUpdatesHook.php:: creationNotify() Called by the after_relationship_save logic hook in cases
But it seems to be executed 2times.

Is there any way by UI / By coding, we can make achieve this?

You can use a logic hook. Here are some links that should help you to achieve it:
