Nuisance Call Handling

Nuisance Call Handling

Effortlessly block annoying telemarketers and robocalls

Are your subscribers tired of receiving nuisance calls from telemarketers and autodialers (robocalls)? As the service provider, you have the opportunity to solve these problems for your customers by leveraging REDCOM’s powerful nuisance call handling features available on the REDCOM HDX/SLICE® family of products. Offering nuisance call avoidance to your customers as chargeable features provides you with the opportunity to drive additional revenue while simultaneously boosting customer satisfaction.

A multi-layered strategy can be implemented to drastically reduce — or even completely eliminate — these intrusive calls. Nuisance calls can be addressed at the network level, subscriber level, or be combined for a robust handling strategy.

Network Level

Incoming calls can be evaluated prior to being presented to the end subscriber. Common nuisance call tactics involve employing Caller ID spoofing to mislead the subscriber into believing that the caller may be legitimate. The techniques used include several methods for changing the Caller ID. The caller may spoof the originating number to appear as if is from a number local to the target subscriber. The number may also be changed to an unrecognizable number (e.g. 1234).

Using the HDX/SLICE translator, the Automatic Number Identification (ANI) of every incoming call can be analyzed to determine the legitimacy of the call. If the ANI is represented as local or unrecognizable, it can be blocked before reaching the end subscriber. In addition, known nuisance numbers can be specifically targeted and blocked with the implementation of a black list.

Block Nuisance Calls at the Network Level

Subscriber Level

Over and above the network level handling, the subscriber can be provided with additional tools for attacking nuisance calls. These capabilities can be implemented individually or completely for each subscriber depending on their needs.

Anonymous Call Rejection

In the event that a caller blocks their caller ID entirely, Anonymous Call Rejection (ACR) can be used by the subscriber to prevent these calls from reaching them. Legitimate callers will be required to enable Calling Number Delivery (CND) in order to ring through to the end station.

White/Black List

Selective Call Acceptance (SCA) and Selective Call Rejection (SCR) can be used to create white and black lists to allow or block specific callers. Numbers on the SCA list will bypass the process and ring through to the station. Numbers on the SCR list can either be blocked directly or proceed to the audio CAPTCHA prompt for further screening.

Audio CAPTCHA Prompt

CAPTCHA is a common method used to distinguish humans from computers. Typically, a prompt is presented that only a human will be able to bypass. In this case, REDCOM’s Telemarketer Do Not Disturb (TDND) feature can be used to provide the CAPTCHA prompt. If the end user subscribes to the TDND feature, a prompt will be presented to all incoming calls informing them that the subscriber does not accept calls from telemarketers and to dial a 1 to continue. Legitimate users are able to dial the required digit and will be connected. Robo calls, however, will timeout and will fail as a result.

Global vs Subscription

Depending on the business model this layered service can be provided globally to all subscribers, through a bulk subscription, or with individual subscriptions to each feature.
