Unlimited scalability

Due to its client-server architecture, VOCORD Phobos IPtel is a perfect solution for deploying geographically distributed telephone conversation recording systems with nearly unlimited number of audio channels and huge archives with storage capacity of up to 10 mln of records. VOCORD Phobos IPtel has a flexible configuration and can be expanded without interruption in operation of the entire system.

Data security

VOCORD Phobos IPtel supports archiving operations.

The data writes can be:

  • Distributed between record servers for load balancing purposes
  • Backed up to all servers for reliability improvement purposes.

In case of failure of one of the servers, the system will automatically find a next working server and store data to it.

VOCORD Phobos IPtel supports full event logging, 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 user 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
