Say Goodbye to Telemarketing RobocallsWhat is a Robocall?
If you answer the phone and hear a recorded message instead of a live person, it’s a robocall. If you’re getting a lot of robocalls trying to sell you something, odds are the calls are illegal. Many also tend to be scams.

What is an Illegal Robocall?
The law states that many telemarketing robocalls are illegal without prior, express written consent from you.

Non-profit, tax-exempt organizations, political calls, and emergency robocalls are legal for landline phone numbers without written consent; however, most political organizations and non-profits do need your consent to call mobile phone numbers.

Emergency or health-related robocalls are exempt for both landline and mobile phones.

What is Spoofing?
Spoofing is when a caller deliberately falsifies the information transmitted to your caller ID display to disguise their identity. Scammers often appear as an incoming call from a local number you may already know and trust. These calls are generated outside of HCTC’s network.

Robocall Blocking: HCTC is committed to combating unlawful Robocalling.  As of June 2021, we are attacking this problem in two ways:

  • HCTC implemented a new software providing robocalling analytics and reputation scoring of our network’s outbound traffic.  This scoring is used to identify suspected illegal robocalls and identify their source.
  • HCTC is now offering Telemarketer Call Screening (TCS) to our members for Free!

Robocall Blocking: How it Works with Telemarketer Call Screening (TCS)Robocalls

  • When an incoming call appears to be a “local” number but is actually originating “outside” of HCTC’s network, the caller will hear the following announcement: “The number you have reached does not accept calls from Telemarketers. If you are a Telemarketer, please add this number to your Do Not Call List and hang up now. Otherwise, please press ‘1’ to complete your call.”
  • Approved callers, like your friends and family, may hear the announcement the first time with no further calls being intercepted.

What do you need to do to activate Telemarketer Call Screening (TCS)?
If you currently subscribe to this feature, you do not need to do anything. If you wish to subscribe to TCS, contact us Monday through Friday during normal business hours to activate this feature.

Is there a charge for Robocall Blocking?
