Face time calls Fail from IPhone to IMac

Question

I am new to face time and not sure what I am doing wrong.  I can make a face time call from my IMac to my IPhone.  When I try facetime from my IPhone to IMac the IMac face time app rings, but when you try to answer the call always fails.  On the IPhone it says that I am busy.  What am I doing wrong?

You're welcome, I'm glad that I could help!
On a side note, if anybody is redirected here from a search engine or elsewhere; the "is busy" message in FaceTime when you clearly are not is almost entirely based on the shared Email (associated with your Apple ID) problem. For example:
Say you have an iPad 2, a iPhone and FaceTime on your MacBook and your iMac in your household, the iPad i.e. is used by your daughter/son, the iPhone and the iMac is used by you and the MacBook is used by your husband/wife. But all of the devices use the same Apple ID (yours).
It helps to associate different Email addresses with each device but not with any other of the devices so any device can be called from another one. As soon as you understood the concept of the solution from the original problem it should be easy to set it up perfectly.
Let's say you have entered the Email addresses on FaceTime in the following manner:
iPhone & iMac: [email protected]
MacBook: husband/[email protected]
iPad 2: daughter/[email protected]
When the iPad 2 calls [email protected] the iPhone and the iMac will ring but you can only pick up on one of the devices. The iPad can also call the MacBook via husband/[email protected] The MacBook can call the iPad via daughter/[email protected] and both the iMac and the iPhone via [email protected] The iPhone can call the MacBook, the iPad but not the iMac (the message "user is busy at the moment" will be displayed). The iMac can call either the MacBook or the iPad but not the iPhone.
As said before: All you need to understand here is the concept, the rest comes naturally.
