[asterisk-users] STIR/SHAKEN

To be honest, that is the logic we ended up with, and are dumping our 
LCR.  The savings aren't worth the headache.  We don't have 1M numbers, 
but we have a significant number.  We can't quite get down to one 
carrier (and don't really want to), but we can keep outbound calls on 
the carrier that "owns" them, and not worry about this.
