ADPCM - Adaptive DPCM (ADPCM) is a variant of DPCM (differential pulse-code modulation) that varies the size of the quantization step, to allow further reduction of the required bandwidth for a given signal-to-noise ratio.

API - In computer science, an application programming interface (API) is an interface that defines the ways by which an application program may request services from libraries and/or operating systems.

Archiving - An archive is a collection of historical records, and the location in which the collection is kept. Archives contain records (primary source documents) which have accumulated over the course of an individual or organization's lifetime.

Calling Line ID / CLI - In some countries, the terms caller display, calling line identification presentation (CLIP), call capture, or just calling line identity are used; call display is the predominant marketing name used in Canada (though customers often call it caller ID). The idea of CNID as a service for POTS subscribers originated from automatic number identification (ANI) as a part of toll free number service in the United States.

CAS - Channel Associated Signaling (CAS), also known as Per-Trunk Signaling (PTS), is a form of digital communication signaling. As with most telecommunication signaling methods, it uses routing information to direct the payload of voice or data to its destination.

Cluster - In computer file systems, a cluster is the unit of disk space allocation for files and directories. In order to reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors, but contiguous groups of sectors, called clusters.

CDR - A Call Detail Record (CDR) is the computer record produced by a telephone exchange containing details of a call that passed through it. It is the automated equivalent of the paper toll tickets that were written and timed by operators for long distance calls in a manual telephone exchange.

CTI - Computer telephony integration, also called computer–telephone integration or CTI, is technology that allows interactions on a telephone and a computer to be integrated or co-ordinated. As contact channels have expanded from voice to include email, web, and fax, the definition of CTI has expanded to include the integration of all customer contact channels (voice, email, web, fax, etc.) with computer systems.

Compression - In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than an unencoded representation would use through use of specific encoding schemes.

[edit] H

Hertz - (Hz) is a measure of frequency, that refers to the ‘number of cycles occurring per second’

[edit] I

ISDN - Integrated Services Digital Network is a telephone system network. Prior to the ISDN, the phone system was viewed as a way to transport voice, with some special services available for data.

[edit] J

[edit] K

KWS - Key Word Spotting. Slower processing, basic unit is a word, the matching between the set of phonemes in the audio and the predefined words list phonetic representation is done during processing.

[edit] L

LVCSR - Large-Vocabulary Continuous Speech Recognition. Much slower processing, since the basic unit is a set of words (bi-grams,tri-grams etc..), it needs to have hundred of thousands of words to match the audio against. The output however is a stream of words, making it richer to work with. It can surface new business issues, the queries are much faster, the accuracy is high than in any of the other methods. Most importantly because the complete semantic context is in the index you can find and focus on business issues very rapidly.

[edit] M

Maker/Checker - Maker-checker (or Maker and Checker, or 4-Eyes) is one of the central principles of authorization in the Information Systems of financial organizations.

MD5 Fingerprinting - In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard, MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files.

[edit] O

On / Off hook - The condition that exists when a telephone or other user instrument is in use, i.e., during dialing or communicating. Note: off-hook originally referred to the condition that prevailed when telephones had a separate earpiece (i.e., receiver), which hung from its switchhook until the user wished to activate it. The weight of the receiver no longer depresses the spring loaded switchhook, thereby connecting the instrument to the telephone line.

OS Hardening - OS Hardening is the process to address security weaknesses in operation systems by implementing the latest OS paches, hotfixes and updates and following procedures and policies to reduce attacks and system down time.

PBX - A private branch exchange (PBX) is a telephone exchange that serves a particular business or office, as opposed to one that a common carrier or telephone company operates for many businesses or for the general public.

PCI (1) - Conventional PCI (part of the PCI Local Bus standard and often shortened to PCI) is a computer bus for attaching hardware devices in a computer. These devices can take either the form of an integrated circuit fitted onto the motherboard itself, called a planar device in the PCI specification, or an expansion card that fits into a slot.

PCI (2) - The Payment Card Industry (PCI) denotes the debit, credit, prepaid, e-purse, ATM, and POS cards and associated businesses.

PCM30 / PCM32 - PCM30 describes an application of pulse-code modulation (PCM) procedure in which an analog signal is binary coded. To apply it, for example, when making calls.

Real-time monitor - Real-time monitoring of all (or selected) applications running on the computers within the organization in order to detect unregistered or unlicensed software and prevent its execution, or limit its execution to within certain hours.

'REV 'drives - REV is a removable hard disk system from Iomega for Small Medium Business and Small Office Home Office users who require fast and reliable back ups.

Rijndael 256 bit audio encryption - In cryptography, the Advanced Encryption Standard (AES) is an encryption standard adopted by the U.S. government. The standard comprises three block ciphers, AES-128, AES-192 and AES-256, adopted from a larger collection originally published as Rijndael. Each AES cipher has a 128-bit block size, with key sizes of 128, 192 and 256 bits, respectively.

Example: Record by extension number, caller ID received, number dialed, time of day, representative, etc. and even exclude any confidential conversation an organization might have. This system can be set up to automatically send copies of the conversations you define as important via email.
