"Whether a customer communicates with desk phones, smart phones, tablets, laptops or PCs, ShoreTel enables them to choose the device best suited to their needs," said Pej Roshan, vice president of product management at ShoreTel. "The ShoreTel 400 series IP phones incorporate the latest user feedback resulting in new functionality and optimal usability." Visual voice mail simplifies message management and increases productivity by allowing users to scroll through messages to access, listen, respond, delete and save them in any order. With this feature, users can pick the messages they want to listen to and erase or archive them right from the phone screen. The intuitive user interface of the 400 series IP phones extends the proven ergonomic advantages of ShoreTel IP phones. Specifically, the display is closer to vertical for better readability with a five-way control for quick navigation through screens and menu options, and the keypad is closer to horizontal for more ease when dialing and using the function keys. The lighter handset offers more comfort and the phones have a smaller footprint for reduced use of space on the desktop.
