Hey, from the examples it looks like the typical usage of
is_subscriber is with $fu ( From User ), however im not 100% sure I want this.
in-fact, I want it to be the Auth User that is used.
After all if a call was Authed, then we authoritatively know what user it is, and I think this should be used over and above the from user ( which could even be set to caller Id in some cases ).
