VOCORD Phobos Audio is a professional telephone conversation (digital, analog phone lines, and E1-stream) recording system.

VOCORD Phobos Audio hardware and software system is designed for:

  • Professional recording of conversations as part of multifunction call processing activity in call and dispatching centers
  • Phone line monitoring by company security services
  • Evaluation of customer service quality in sales, telemarketing and technical support departments of commercial companies

The main advantage of VOCORD Phobos Audio system is a scalable geographically distributed architecture that allows of creating identically reliable and fail-safe audio registrationsystems both for four and several thousands of channels.

VOCORD Phobos Audio systems are installed in: Call Center OJSC “Megafon”, Commercial Call Centers “Vympelkom” JSC, Call Center of the Ministry of Internal Affairs – service 02, Emergency Call service – service 03, call centers of the United Call Center.

Due to the fact that hardware and software components of VOCORD Phobos Audio system are fully Russian-grown technologies, the system is more economical in comparison with analogous recording systems from foreign manufacturers.

Thanks to its reliability, usability and affordability, VOCORD Phobos Audio system has been chosen by more than 400 government institutions and commercial companies in Russia and neighboring countries.

Unlimited scalability

Due to its client-server architecture, VOCORD Phobos is a perfect solution for deploying geographically distributed audio registration systems with nearly unlimited number of audio channels and huge archives with storage capacity of up to 10 mln of records.

VOCORD Phobos Audio build-up is performed by simple expansion in the number of servers without shutting down of the entire audio registration system. In case of breakdown of a separate server, this will not affect the entire system operation.

Data security

VOCORD Phobos Audio supports a complete event logging function: from record deletion to system events.

For any performed operation the notification can be sent to users via message, audio alarm, e-mail or SMS.

The number of users or users groups in the system is unlimited. Access rights for each user or user group can be set up within the accuracy of each attribute, type of operation or data folder.

Data can be copied to external media in manual and automatic modes.

High usability

Intuitive interface allows the operator to run quick search commands, listen, replicate, export, comment and delete audio records. All of these operations can be performed manually or automatically.

Physical links can be combined into logical ones based on the user friendly principle. Specific physical voice-communication links are combined into a singe logical link supporting specified operations. For example, upon activation of one of physical links, recording will be started automatically over all channels included in the logical stream.

Remote work is also supported – via local network or Internet.

Improved quality of recording

Special digital signal processing tools facilitate resolving a noise problem during recording such as background noises in the room and line noises. The system performs noise cleaning in real time, also in a manual mode.

To counter the interference, VOCORD Phobos features a set of digital processing tools:

  • Adaptive broadband and narrowband filters
  • Frequency-domain n-band graphic equalizer
  • Automatic signal level adjustment module

Open program interface

VOCORD Phobos Audio open interface allows the system to be integrated with the third-party programs and to create customized design solutions.
