High volume calls are the nature of the business. So, it’s up to your trusty receptionist or administrative assistant to relay them to the right people. This module is easy to navigate thanks to a 4.3-inch colored screen that will allow you to navigate through your list of contacts. This provides call forwarding, transferring, speed dial, and so many other abilities that makes this unit run like a well-oiled machine. It’s like a telephone switchboard modernized for today’s times. This is the best module for any mid-sized business or large department.
