This "Call Lookup DA" works as "Phone Lookup" but the function is expanded from the standard Phone Lookup. It can find the phone number even if you cannot remember the last name of your classmate. Also you can get the email address of your customer who you remember just his/her company name. Call Lookup DA also can insert the various phone numbers. Note: This is a DA (Desk Accessory) program. To use this, the launcher program that can launch a DA program, like "DA Launcher", is required.
