If you have multiple iDevices logged in using the same Apple ID you can answer calls on any device, that is if you have enabled the 'Calls on other devices' switch on your iPhone's 'Settings' - 'Cellular' option. My wife answers calls on her iPad all the time.

You can also make a call from your iPad even though it doesn't have the traditional phone app installed, just go to your Contacts and tap on whoever you want to call, then when that contact's info comes up tap the 'Call' button below their name.
