When a caller dials a DID phone number, just like direct inward dialing suggests, they are directed immediately to its destination, whether that be to an individual user, a ring group, device or voicemail box. This is helpful in many ways, but especially for salespeople who have prospects, they want to have swift, direct contact with, surpassing any menus or the need to recall an extension number. It also functions great as a direct line to a customer support department. The uses don’t stop there, though, because companies will use VirtualPBX DID phone numbers for everything from VIP clients to preferred vendors and anything between.
