Internet Answering Machine will allow you to hear who"s calling while you"re online, and avoid the cost of an extra phone line. Instead of getting a busy signal, your callers can leave a message that you hear over your computer speakers. By using automatic busy call forwarding, callers are redirected to a voice mail system through the Callwave servers. After your PC downloads the message, you hear the recording and can decide whether or not to get offline. Callwave is a must-have for modem users wanting to avoid paying for a second phone line
