If you have Caller ID and the party calling you has their number blocked, this service blocks that call from coming through and routes it to a recording. NDTC must activate this feature on your line.

You need to reach someone, but their phone is busy. Auto Call Back calls the party you’re trying to reach every minute for 30 minutes.

Your phone rang, but you were unable to answer it in time. With just a touch, Auto Recall will dial the last number that called you.

Call Screening greets your callers with an automated message to press 1 if they are not a telemarketer. If a 1 is not selected, the call will not complete and your home phone will not ring. If a 1 is selected, that caller is added to your “approved list”.

If you send or receive automated calls (appointments, school reminders, etc.), please provide us with those phone numbers to ensure they are added to our company-wide “approved list”.

Home, rental property, or commercial building owners are responsible for the telephone wiring inside the walls. If you find any damage from, for instance, an exposed wire or pests in the walls, you could receive an unexpected repair bill. We’re glad to fix any problem leading to your home at no cost to you, but the law requires that you are responsible for what’s inside the building.

Take advantage of the NDTC Maintenance Service, which can protect you from an unexpected bill for repair work completed inside your walls. Enjoy peace of mind with NDTC’s Maintenance Service.

How It Works

A short tone signals that another person is trying to call you when you are on the phone. The incoming caller only hears the usual ringing sound. You can put one call on hold while handling the second call, or alternate between the two.

To Answer the Second Call

1. If you wish to end the first call, hang up.
2. Your phone will ring and the second (incoming) caller will be on the line.
3. If you want to hold the first call while answering the second call, press the switchhook once, firmly (1/2 second), and release it immediately.
4. You will be connected with the other person on your line. (Use the recall button on Trimline® models.)

Returning to the First Call

To return to the first call, simply press the switchhook once, firmly (1/2 second), and release it immediately. With this method, you can switch between the two calls as frequently as you wish.

How to End Either Conversation

After you have finished talking with either caller, hang up. Your phone will ring and when you answer you will be connected with the person remaining on the line.

To Cancel Call Waiting

Turn on Cancel Call Waiting when you’re making an important call and talk as long as you want with no interruptions. The Calling party will receive a recorded message that the call cannot be completed. After you finish your call, Call Waiting returns automatically when you hang up the phone. Cancel Call Waiting assures you of uninterrupted phone calls during important conversations, when talking long distance.

Instructions:

1. Listen for a dial tone.
2. Dial 70 #.
3. Listen for three short tones, followed by a normal dial tone.
4. Dial a telephone number.

During a Call...

1. Press the switchhook (the button that hangs up the phone) for one second.
2. Dial 70 #.
3. A tone will be heard and you will be automatically reconnected to your call.

  • A short ring will be heard whenever your number is called to remind you your telephone calls are forwarded, but you will be unable to answer these calls to your initiating telephone until you deactivate Call Forwarding.
  • Don’t forget to tell the person who will receive your calls that you are using Call Forwarding, especially if you will not be where your calls will be forwarded.
  • You pay applicable charges, if any, for calls forwarded from your telephone.
