Overview And Requirements:
Customer Demand: Recording 10 Tadiran Digital Telephones
Selection model: MDD1016
As we all know, the need to record telephone calls has become more and more prosperous in recent years. This application area was originally created for security considerations and later for the recording and tracking of responsibilities. With the further development of the communications industry, telephone recording systems have also been applied to a wider range of fields. The telephone recording system technically includes the following points:
1. Make undisturbed recordings of both sides of the call.
2. Listen directly to any line call.
3. Standard (or unique) sound format, multi-channel recording playback.
4. Can customize the way recording starts.
5. Highly efficient voice compression technology, up to 8 times the shelf-quality compression.
6. Support analog, digital, wireless and other telephone line recording.
7. Flexible and fast query and retrieval, support for remote query and monitoring.
8. Provide effective data backup methods.
Typical Application:
1. Support most digital exchanges at home and abroad
Alcatel、Avaya、Ericsson、Harris、intertel、ISDN、Iwatsu、LG、Mitel、NEC、Nortel、Panasonic、Philips、Samsung、Siemens、Tadiran、Toshiba。
2. A variety of recording start method
The system has built-in voltage control, code control, voice control, D-channel, signal analysis control, and network control. The control components provide standard API interfaces. Users can develop control methods based on this interface and customize them according to user requirements.
3, strict authority management mechanism
The recording system is divided into multiple operation modules. The user can freely allocate these modules to the account, lock an account, restrict the operation of certain channels on the account, and set the validity period of the account. After the expiration date, the user cannot log in.
4, multi-channel real-time recording
Simultaneous recording of multiple telephone or audio lines (1-248 channels, the general recording system can only achieve 64 channels while recording), each line does not affect each other, respectively stored, does not affect the normal call of both parties, recording time Only limited by disk capacity.
5, efficient compression technology
The system has an optimized voice compression algorithm that can simultaneously record up to 248 lines and perform MP3 compression. After using the MP3 format, the recording space occupation can be reduced to 1KB/sec, which is 3.5MB/hour, effectively reducing The overall cost of the system.
6, optimized write buffer technology
The system has its own special file format and good write buffer technology, making the system able to run freely under large capacity and large traffic.
7, advanced hard disk management mechanism
The system can automatically manage all hard disk space and network storage devices (NAS) of the operating system. It also has an automatic disk rewrite function and disk space alarm function. When the capacity is insufficient, the oldest recording file will be automatically deleted. The capacity of the deleted file is set by the user, and the maximum retention period of the recording file may also be set. When this limit expires, it will be deleted automatically, eliminating the need for manual maintenance.
8, convenient recording audit function
The system provides a query condition generator, which can quickly retrieve recording records according to database fields. You can play any one recording or select multiple recordings in sequence to play. You can save the query results in Excel to facilitate statistics and output reports.
9, a perfect backup mechanism
The system has a synchronous backup function. In addition, users can regularly back up important recordings at any time. Backup devices can be used in parallel or in series. Backup media include rewritable CDs, DVDs, MOs, network virtual disks, and hard disks.
10, multi-channel remote audit function
The user can monitor and query recording files through the local area network and the Internet, play remote recording files through a sound card in a remote place, and monitor the current call of any channel in real time.
11. Accurate channel feedback information
The system has an incoming call display function, and can accurately determine the main callee. The user can obtain work status information of all channels, voltage, telephone number, recording time, status (break, call, idle, recording, etc.) at the local or remote place. Unused, unused for a long time, etc.
12. Multi-channel alarm function
All kinds of alarm events defined by the system can be alerted through email, network messages, SMS, telephone, fax, voice, etc., and the operating status of the system can be known no matter where the manager is.
13, advanced system architecture
The recording equipment adopts the world's most advanced B/S technology to manage and monitor the server through the workstation's browser. The voice recording of the server and the management of the system are performed on two kinds of devices respectively, which greatly improves the reliability and security of the system. In other words, even if the LAN and the workstation have problems due to malfunction or misoperation, the server will not be affected. Voice recordings do not suffer from crashes and data loss.The user can monitor and query recording files through the local area network and the Internet, play remote recording files through a sound card in a remote place, and monitor the current call of any channel in real time.
