IP phones offer a richer set of features than regular phones. For example, they give you access to a central company directory, making it easy to search for staff members and call them without referring to out dated paper lists. “Click to dial” then makes it easy for you to make a call without keying the full number.
When you have your phone on “do not disturb” or “call forward” this is visible across the entire company, so everyone knows your status.
A receptionist will be able to see the status of each user, irrespective of their office location. Rather than blindly passing calls on your callers can be informed that your line is busy and given the option to wait or leave a message.
There are also huge benefits in the administration of your phone system, making it easier to manage add-ons, moves and changes.
