TDM Recording Technologies

  • Physical Connectivity: Each trunk in TDM environments requires a physical connection. Digital trunks efficiently handle multiple voice channels over one circuit.

  • Line Interface Cards: Interface seamlessly with digital and analog trunks using line interface cards for effective call recording.

  • Recorder: Gathers detailed call information via CTI or SMDR, including date/time, extension details, agent information, caller ID, and dialed number.

  • Selective Recording: Record only relevant calls passing through the trunks, eliminating internal-to-internal calls.


Passive recording is transparent integration that involves monitoring the network for audio and call information without impacting the telephone system.


Active recording is switch-level integration requiring additional data from CTI applications for extended call controls, providing greater flexibility and functionality.

Digital & Analog Extension Side Recording

  • Recording of Non-IP Extensions: Passive recording for non-IP extensions on a PBX.

  • Cost-Effective: Generally more cost-effective than CTI integration.

  • Compatible Recording Card: Utilize a compatible recording card installed on the RECITE server and bridged to phones via a patch panel.

  • Comprehensive Recording: Record all calls made to and from an extension, including internal and external calls.

VoIP Call Recording

VoIP Recording Overview:

Voice over Internet Protocol (VoIP) recording, a vital component of telephone recording or voice logging, has evolved beyond its initial use in call centers to become indispensable for businesses across various industries. This technology converts audio into digital packets and subsequently into IP packets, enabling organizations to achieve diverse objectives.

Key Reasons for VoIP Recording:

  • Legal Compliance: Mitigate company vulnerability to lawsuits by maintaining recorded evidence.

  • Regulatory Adherence: Ensure compliance with telephone call recording laws.

  • Security Enhancement: Bolster overall security by monitoring and recording voice over IP call traffic.

  • Training and Performance: Facilitate employee training and conduct performance reviews using recorded interactions.

  • Control and Alignment: Enhance control and alignment of employee activities within the organization.

  • Data Verification: Verify data integrity through recorded voice over IP communications.

  • Knowledge Sharing: Share critical data within the organization for improved collaboration.

  • Customer Satisfaction: Evaluate and enhance customer satisfaction by analyzing recorded interactions.

  • Agent Morale: Boost call center agent morale through performance feedback and coaching.


  • Passive VoIP Recording is achieved by connecting the call recorder to the Switched Port Analyzer (SPAN) port, which allows our solution to monitor all network traffic and target only the VoIP traffic to record by either Mac Address or by IP Address.
  • Through the SPAN port, the recorder will “sniff” for signaling and Real Time Protocol (RTP ) packets that have the identifying information contained in the headers of the packets that are targeted to be recorded.
  • Depending on the capture location of the RTP packets, the Numonix recorder can record either all internal and external calls, not including internal peer-to-peer call scenarios, or all calls including internal peer-to-peer calls.

Active VoIP

  • Active VoIP Recording is achieved through a switch-level integration in which the Numonix solution becomes an “active” participant within the call.
  • The interaction of the recorder to the PBX provides greater flexibility and functionality.
  • Generally, it is not required to do port spanning as PBXs will provide methods in which to fork media to the Numonix recorder.
  • Active VOiP recording can capture both in/out bound and internal traffic
  • Considerations: Requires VLAN setup, potential issues with phones on different VLANs
