The SP3 has three call appearances, allowing you to maintain three voice conversations simultaneously. Each call appearance is treated as a separate call so it is easy to know which call you are on, and you can switch between calls by a click of a button. The Auto Accept feature allows you to answer any incoming call without the need to even touch your computer.

The phone book allows you to store phone numbers and information regarding each number. The call log presents a list of the 10 numbers dialled, received, and missed. Each entry in the log displays the date and time stamp, duration, and the caller ID.
