how do I enhance my campaign if I have created a call extension
By creating a call extension, you are allowing the online users to reach you directly with your business phone number which is always good because there are segment of users who prefer calling the business owners before making a purchase or opting for any service. So it's an added facility which Adwords is giving in the name of various ad extensions and call extensions is one of them.
You can read more about call extensions in this article: https://support.google.com/adwords/answer/2453991?hl=en
Hope that helps!
