No Caller ID Vs Unknown Caller

Caller Id or Caller Identification is a service from the telecommunication carrier company. It is obtainable in all telephone services including VoIP (Voice over IP). The function of a caller ID is to transmit the caller identification from the caller’s telephone device to the recipient’s telephone device when a call is initiated. The caller identification includes a Caller ID Name (abbreviated as CNAM), and the caller’s phone number. The transmitted information will be displayed on the recipient’s telephone device before answering the call. Definitely, there are situations that display ‘No Caller ID’, or ‘Unknown Caller. Many will be receiving such calls. Both the calls represent a masked caller. In this article, we will talk about No caller ID vs Unknown Caller.

The former is purposefully hiding the identification information of the caller by making use of their own phone features. The latter is because the network is incapable to find out or interpret the caller’s identification. Also in the case of ‘unknown caller’, the standards for the CNAM database management across different carriers will be different. Thus the updating of the CNAM database may take time, and thus the network will not get the information immediately.

Caller ID

Caller Id is a service that can display a 10-digit telephone number and a name with fifteen characters. This is used for identifying the caller. For an average individual, the caller Id is useful for screening the calls and deciding whether to attend the call or not if an unknown person is calling. If an unfamiliar name is calling, then no need to attend the call. But for a business, if an unfamiliar name is calling, then it can bring more promotions for the business, and thus conversion rates occur. Thus caller Id is a business solution. Also for a business, they have to set a caller ID for their phone number to make awareness of their brand name.

One can decide whether to set or not set the caller ID. If the phone number holder wishes to expose the phone number and identity to the public, then it is better to set the Caller ID, otherwise not required to be set. Similarly in the case of a business, if the business needs to make more brand awareness to the public and thus make promotions, then it is better to set the caller ID for the business phone number. Setting caller ID involves a few simple steps to be followed. For smartphones, the Caller ID can be set from the phone settings or can be set by using the third-party apps available at the Play store (Google Play for android phones).

CNAM Database

CNAM or Caller ID Name database or line information database (LIDB) is a database used by telecom companies to store and retrieve the data useful for displaying the caller ID. It is actually a collection of names and associated phone numbers. The telecom carrier is responsible for accessing and displaying this information. The telecom carrier makes a look-up into the CNAM database using the key as the caller’s phone number. Then accesses the name present in the database that corresponds to the phone number for the use of the Caller ID display. If the name is not available, then the database query may return the geographic location or city of the caller.

If any change is made in the caller ID by the caller, then it will not be reflected immediately in the CNAM database. It can take 24 to 72 hours to get updated. In the case of landline phones, the CNAM is always enabled, but in the case of mobile carriers, there are some restrictions existing. As a result of these restrictions, the carrier providers will not be able to display the information all the time.

Setting Up the Caller ID

Caller ID set up in Landlines

The landline providers will be setting the caller ID information from the name associated with the caller’s landline number. In this case, if the name is to be changed, then the number holder should have to contact the phone carrier company and request an update. The company customer care sections may change the name or create secondary information with the same phone number and the new name given to them.

 FAQs

Q1. Where do the details of Caller Id information store? who is responsible to display the Caller ID information?

Ans. The Caller ID information is stored in a database called as CNAM database. When you make a call, you are the caller. The telecom carrier company is responsible to look up your name in the CNAM database and transmitting it to the recipient’s phone. If the operation failed to detect to access your identification information (our name), then either ‘No caller ID’ or ‘Unknown Caller’ will be displayed depending on the reason that makes the operation fail. If you have hidden the ID information using your phone features, then ‘No caller Id’ is transmitted to the recipient’s phone. Or if the carrier company could not interpret the ID due to certain restrictions, then the recipient gets the display as ‘Unknown Caller’.

Q2. How do identify and block the spammers?

Ans. If it is coming from an unknown source, then it is not safe to continue with the call. If the phone number is not hidden, then you can block it using the ‘block the number’, option available in the phone app. Otherwise, you can use third-party software and find out whether it is a useful call or not. Then if it is not a good call you can block it from the third-party app also. But while using a third-party app for these, you have to give permissions to access certain options (devices),  available on your mobile. Otherwise, those apps cannot complete the tasks.

Q3. Why unknown calls are not favorable?

Ans. Unknown calls are not favorable because someone is making attempts purposefully to trap you or get some favor from you. An unidentified or hidden ID will not come with a positive attitude. It may be for somebody’s business promotions and not for your goodwill. The phone number hiding is a way from the caller’s side to become anonymous to others. A person who is calling for your best will surely expose the identity and will surely have a Caller ID whether it is an individual or a business.
