PhoneTray uses your modem to identify the callers before you answer the phone. You must subscribe to the caller id service from your phone company and have a CallerID capable modem.

When a call comes in, PhoneTray rings and shows a balloon with the caller's name and number. The program can also display full screen so you can see who's calling from a distance. PhoneTray also announces incoming calls using text-to-speech engine. You can select to announce caller's name, number or both.

PhoneTray allows you to assign names to your frequent callers. The name you assign will be displayed and announced instead of Caller ID info. You can set a different ringtone for each caller or type of callers. 20 ringtones are included with the program

PhoneTray logs all your incoming calls. It keeps the date, time, name and phone number of each call. You can view a complete call history or calls received today, this week or this month. You can select what type of calls you want to see - all calls, local calls, long distance calls etc.

Call history is stored in a standard CSV file and can be edited and exported to other programs using Microsoft Excel.
