Connect an external Voice Mail / Auto Attendant system to your telephone system so that each telephone set has its own voice mail box, which can also be accessed remotely. Callers that get through to a voice mail box has options to call the operator or the mobile number of the owner of the voice mail box before leaving a message.
Using an Auto Attendant will free up your receptionist for more streamlining of your calls. A typical announcement could be as follows; “Thank you for calling XYZ Company. If you know the extension number you require, please dial it now. For sales, please dial 1. For accounts, please dial 2. For Distribution, please dial 3. For reception, please dial 0.”
