CDR and CMR
Cisco Unified Communications Manager produces two types of records which store call history and diagnostic information, as follows:
Call detail records (CDR) – Data records that contain information about each call that was processed by CallManager.
Call management records (CMR) – Data records that contain quality of service (QoS) or diagnostic information about the call. Also referred to as diagnostic records.
Both CDRs and CMRs together are referred to as CDR data. CDR data provides a record of all calls that have been made or received by users of the CallManager system. CDR data is useful primarily for generating billing records; however, it can also be used for tracking call activity, diagnosing certain types of problems and capacity planning.
CDRs contain information about call origination, call destination, the date and time the call was started, the time it actually connected, and the time it ended. A call is considered started or originated when the caller goes off-hook. The call is considered ended when either the caller or the called party goes on-hook. CMRs contain information about the amount of data sent and received, jitter, latency, and lost packets.
CUCM or Cisco Unified Communications Manager
Cisco Unified Communications (UC) is an IP-based communications system integrating voice, video, data, and mobility products and applications. It enables more effective, secure communications and can transform the way in which we communicate. UC represents a communications paradigm shift like that of the invention of the telegraph. UC removes the geographic barriers of effective communications through the use of voice, video, and data integration. Business can be conducted with a fluidity that progresses and evolves with you. Information has been at our fingertips for a long time, but UC enables the sharing of this information to create knowledge and value.
Cisco UC is part of an integrated solution that includes network infrastructure, security, mobility, network management products, lifecycle services, flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communication applications.
Cisco UC can drastically change the bottom line of business by creating more effective communications without losing the personal nature of a face-to-face conversation. More effective communication leads to reduced time to market and nimble transformation of business processes through collaboration.
Toll fraud, aka VoIP fraud, is when hackers are able to access your UC phone system and make fraudulent long distance calls from your account.
Long distance, per-minute charges add up fast. A whopping $38.1 billion in losses were attributed to toll fraud in 2015 alone.
Although the best VoIP providers offer round the clock fraud monitoring, it is still important for business owners to be aware of potential vulnerabilities and take steps to prevent toll fraud.
