A call detail record (CDR) is a data record created by a telephone exchange or other telecommunications equipment that records the specifics of a phone call or other telecommunications transaction (e.g., text message) that travels through that facility or equipment. Time, length, completion status, source number, and destination number are among the call’s different attributes. It’s the computerized version of paper toll tickets printed and timed by operators for long-distance calls to a manual phone exchange.

The Call Detail Record (CDR) is a detailed record of all phone calls that travel through a phone exchange or other telecommunications equipment. The form is kept by the involved telephone exchange and contains call details such as the time, the duration of the call, the source and destination numbers, the call’s complete status, and so on.

Call detail records are useful for generating income for the telephone company. When service providers and law enforcement need them, they’re critical. CDR is also used for VoIP, and it records all usage information such as the origin and destination of calls, the length of IP usage, and the total amount charged for the billing period. Telephone exchanges keep call detail records for individual customers/users by exchanging information in the form of tickets.

CDR stands for complete call detail record. A call detail record (CDR) is a computer record maintained by a telephone exchange or other telecommunication equipment that includes a full description of all telephonic calls and other communication transactions (such as text messaging) that pass through that facility or device.

The call detail record contains important information about when and how your company’s phone system is used. Some frequently asked questions concerning CDRs for Reporting and Billing are included below. A Call Detail Record (CDR) is a file that contains information about phone calls. For reporting and invoicing purposes, CDR reports can provide businesses with reliable information about where, when, and how calls are made.

Call detail records are used for a variety of tasks. They are critical for revenue generation for telephone service providers since they serve as the foundation for issuing telephone bills. Call detail records can help law enforcement identify suspects by disclosing characteristics such as a person’s relationships with acquaintances, communication and behavior patterns, and even location data that can determine a person’s whereabouts. Throughout the call, Call detail records are used by firms with PBX telephone systems to manage long-distance access, monitor telephone usage by department or office, and list incoming and outgoing calls.

Call detail records (CDRs) store information about phone calls, such as the caller (name and number), the person who was phoned (name and number), the caller’s Date and time, the call, and typically dozens of use and diagnostic information items (for example, the features used and the reason for the call termination).

CDRs are gathered regularly to assess utilization, capacity, performance, and general clinical reports. Exceptions to usual calling patterns, such as out-of-call, foreign calls, major deviations from the prior reporting period, and call destinations that do not match normal calling patterns for the company, are easy to discover with this kind of data.

What is CDR?

A CDR contains metadata about a phone number and how the user interacts with the phone system. This metadata often comprises the following:-

  • When the phone call was made (Date and time)
  • how long did it go on? (in minutes)
  • Who was it that called whom? (source and destination phone numbers)
  • What kind of call did you make? (inbound, outbound, toll-free)
  • Cost of a phone call (based on per minute rate)

SMS messaging metadata and any other official communication transmissions may be included in the CDR. The CDR does not reveal the substance of the message or call. The call detail record indicates whether or not the call or message occurred and the basic call attributes.

What is the significance of CDR?

Every billable communication transmission on your phone system is listed in a CDR log. This enables phone providers to create your phone bill while also allowing you to keep track of how and when your phone system is used. Businesses typically utilize them to help with call reporting and billing.

Billing departments use CDRs to resolve disputes, track how funds are spent, and track telephone usage. The IT department can also use the CDR to see if there was a phone service outage. CDRs can be used to discover calling patterns and learn more about how employees use their phones. Examining patterns and trends enables a company to make better management and personnel decisions.

What information is contained in the CDR report?

The data in a CDR report is usually broken down by user or phone number. A CDR report for a single user can reveal specific metrics, such as call volume and minutes. A call detail report (CDR) for a phone number gives you a bird’s eye perspective of how your phone is used across your company. Creating CDR reports for individual employees can help you figure out who spends the most time on the phone, how long their calls last, and how much money they spend per call.

This can lead to better workforce management and cost savings for your company. On the other hand, a CDR record for a given phone line can reveal how much individual offices or groups spend on calling minutes. This is beneficial if your company has many phone lines for different locations or departments. This report gives you a comprehensive picture of your company’s calling operations.

Is there anything more in the CDR report that I should know about?

CDRs are generally avoided by communication transmissions that do not cost money. SIP-to-SIP calling is free with many Voice over Internet Protocol (VoIP) services. When a VoIP phone calls another VoIP phone without using the Public Switched Telephone Network (PSTN), this is referred to as “direct dialing” (PSTN). Because these calls are not billed, they are not recorded on the CDR.

On the other hand, calls to landlines, mobile phones, and foreign numbers are constantly documented because they are charged per minute. On the other hand, cloud phone solutions frequently provide a feature that allows you to check call logs for unbilled Internet calls. This information is commonly discovered in your web phone service’s “call history” or “recent calls.”

What is the best way to create a CDR report?

CDR reports are typically supplied as part of a VoIP business service’s reporting tools. Admin users can access a web portal and examine and download information for a specific period. The CDR is also listed on the formal phone bill that your carrier sends to you.

Who can benefit from CDR Full Form 

CDRs for employees or phone numbers can be generated by anyone with administrator capabilities on your corporate phone system. The 4th Amendment does not protect CDRs, and law enforcement can access them without a warrant.

Call detail data can establish calling trends between networks of people, even if they don’t define call recordings or location information. A New Yorker article explored the efficacy of call detail records in criminal trials. It was discovered that CDRs “give the kind of information that helps cell providers run their networks, not trace phones.”

I am calling for data that is more accurate.

Call detail records to provide a lot of information about how you used your phone. You can utilize the information to resolve billing disputes, track when, where, and how you use your phone system, and verify billing issues. The call center reporting services might be worth checking if you want a more in-depth look into your calling behavior. OnSIP’s Enhanced Queue functionality, for instance, includes a real-time dashboard of your multiple calling queues and custom reporting.

CDRs can analyze previous calls, but enhanced queuing allows you to communicate with staff and consumers as the conversation progresses. To optimize your business phone system, use the dashboard to streamline average caller wait times, historical information, and call center services. This data can evaluate various call monitoring indicators to improve your team’s phone performance.

How can WHO make use of ACC for CDR?

The CDR is inaccessible to the general public. CDRs may be available to state and federal law enforcement agencies in extreme instances. The CBI, other intelligence agencies, the Income Tax Department, and other anti-terrorism authorities are among the organizations that have access to it.

Before they can access the call detail records, they must first obtain the necessary permissions. There have been a few cases where the CDR has been accessed. The High Court allowed the investigating agency to send the topic to the CDR for investigation in 2014.

What is the CDR procedure – CDR Full Form 

Investigative authorities may obtain immediate call detail data in extreme incidents such as murder, rape, or terroristic threats. In such extreme instances, mobile network service providers only allow for a half-hour response time. It takes around a year to get access to the CDR in typical conditions. If you require the information, you must obtain urgent special approval from a senior police officer.

The Call Detail Record (CDR) functionality generates text records of call data. Calling and called numbers, call origination/connect time, call disconnection time, disconnect reason, DLCI fields to identify the originating PRI, and carrier (b) channel used are all included in the data entered. Normal calls, that is, calls that were completed successfully and calls that were unsuccessful, both have CDRs.

To avoid file overwrites and disk difficulties, CDRs are kept as files that a StrataView Plus workstation can upload. The DAS server shelf can hold up to 10 CDR files at any given time. Each CDR file comprises CDRs gathered over the period specified by the CDR interval. (Change the CDR configuration section in the Understanding the DAS command line interface to set the CDR interval and several CDR files.)

Each CDR file will hold 30 minutes of data if the CDR interval is set to 30 minutes (the default). Calls accepted within a 30-minute break will be routed to CDR. The call activity rate and the CDR configuration setting will determine the size of the CDR files. Every 30 minutes, the StrateView Plus Workstation DAS Server uploads, archives, and archives CDR files from the shelf. Before removal, these archived files are retained for 30 days on the StrataView Plus workstation.
