Is the default behavior of the Opening Call Handler to allow outside callers to reach VPIM Subscribers and VPIM Blind Addresses (via having Delivery Location Dial ID & Remote Mailbox Number)?
Assuming that is the default behavior of call handlers, can the CoS of call handlers be safely changed to apply restrictions based on Delivery Location Dial ID? How would one go about doing that?
I'm trying to determine if you're forced to expose total VPIM functionality to outside callers, if it can be limited based on Delivery Location Dial ID, or if it can be limited just to subscribers.
