How to Handle Annoying or Threatening Calls

In an effort to reduce the number of unwanted telemarketing calls, the FCC has provided telephone subscribers the opportunity to register their residential telephone numbers, including wireless numbers, for inclusion in the national Do Not Call (DNC) registry administered by the FTC. You may register, or revoke registration of, your number without charge by calling the FTCs toll free number, 1-888-382-1222 or TYY 1-866-290-4236, from the telephone number you are registering or revoking, or via online by visiting the FTCs website located at The FCC/FTC rules contain an established business relationship exception that permits a company that has such a relationship with you, like ATMC, to call you even if your number is on this national DNC list.

Telemarketer Call Screening is an optional call feature designed to prevent calls from live telemarketers as well as ALL robo-dialed or automated calls. When the feature is turned on, all incoming calls initiate the recorded announcement: "This number does not accept telemarketer calls. If you are a telemarketer, put this number on your DO NOT CALL list. If you ARE NOT a telemarketer, press 1." When the caller presses '1', the call is released to ring through on your line, and that number is automatically added to your ALLOW list.

  • If the caller is a live telemarketer, he is expected to follow the announcement instructions to add your phone number to their DO NOT CALL list, and not press '1'.
  • Robo-dialed or automated calls do not have a live person present to press '1', so those calls WILL NOT ring through on your line.

IMPORTANT NOTE: While this feature prevents unwanted robo-dialed or automated calls such as from telemarketers and political parties, IT WILL ALSO prevent robo-dialed or automated calls communicating wanted messages, such as school closings, doctor appointment reminders, etc. To make sure you get these important calls, you may contact these entities and change your contact number to your cell number. Or, you can add the phone number they use for automated messaging to your ALLOW list.

Use Selective Call Rejection to create a list of up to 30 telephone numbers you want to block. Calls from these numbers never reach you; instead, the calling party hears a pre-recorded message telling them that you are not receiving calls at this time. Subscribe to this feature by calling ATMC Customer Service at 754-4311. To Use Selective Call Rejection:
  1. To turn On or Off: Press *60 and listen for instructions.
  2. If you know the number that has called you: Hang up. Lift the receiver and listen for the dial tone. Press *60 and follow the instructions on how to add the number to your list.
  3. If you DO NOT know the number that has called you: Hang up. Lift the receiver and listen for the dial tone. Press *60 and listen for instructions. Press # 01 #. This will capture the number of the last party that has called and add it to your list.
Use Call Trace if you are receiving threatening calls and you have asked law enforcement to become involved. Call Trace allows you to automatically request a trace of an obscene, threatening or harassing call. After receiving such a call, you simply dial a special code to have the calling party’s phone number printed at ATMC. Subscribe to this feature by calling ATMC Customer Service at 754-4311. To Use Call Trace:
  1. Hang up after receiving the threatening call.
  2. Lift the receiver and listen for dial tone.
  3. Press *57. A recording will tell you if the call was successfully traced or not. If it is successful, call ATMC at 755-1630 and leave your name, phone number, and the date and time of the call traced.
An authorized ATMC representative will pull the information and start a file. Calls that are successfully traced will be added to your file. You must contact us after each successfully traced call. You will be notified when three or more calls have been traced back to the same telephone number. ATMC does not take deterrent action on your behalf. However, we will release your trace information to law enforcement agencies for further investigation.
If you suspect an illegal wiretap or listening device on your telephone, report this to our repair department by calling 754-4317.
