You will see the Grasshopper number that was originally dialed on your forwarding phone. You can also change the setting of any extension to show the Caller ID of the caller. Your phone will ring the same as other calls but by using the Call Announce feature, you will hear our system asking you to press 1 to take the call, 2 to send the caller to voicemail, and 3 to listen to the phone number of the caller. This will allow you to distinguish between a business and a personal call.
