Abstract
The disclosed techniques enable selective forwarding and blocking of calls directed to an alias phone number based on a whitelist, as well as text message alerts triggered by phone calls from unauthorized originating numbers. More generally, the disclosed techniques enable an enterprise system to store contact phone numbers (i.e., alias phone numbers) for users while avoiding storing and managing personal phone numbers for the user. For example, the enterprise system may forward personal phone numbers to an aliasing server configured to generate alias phone numbers based on the personal phone number. The aliasing server may operate as a “middle man” that receives calls directed to the alias phone number and that forwards the calls to the personal phone number when appropriate. The enterprise system may store and maintain the alias phone numbers in lieu of the personal phone numbers.
