  1. Call Alert is a GRID Private ID feature that allows you to send and alert to notify someone you would like to talk to. It is less intrusive than placing a call to the other person immediately, as he or she could be in a meeting. Sending an alert allows the person to  respond accordingly to his or her convenience.
