Just add the people you call back frequently to a special list. That's it.
After this done - there is no any special interface or something else to remember.
You just answer EVERYBODY as usual.
Your android will answer to everybody except the "list-of-your-friends-to-call-back".
If the caller is from the list - your android will call back automatically.
