Record & retain · Eventide

Built for mission critical applications.

A purpose-built recorder for dispatch and control rooms. Logs PTT, talk group and position alongside the audio, so an incident is found by who transmitted rather than by trawling a timeline.

Radio is not telephony with a different plug. A dispatch recording is only useful if you can tell who keyed up, on which talk group, and where they were.

Eventide NexLog records a wide range of radio systems, and Eventide has spent years working directly with the major radio manufacturers rather than adapting a telephony product to the job. That shows up in what gets logged: not just the audio, but the identity of the radio that transmitted, the talk group it was on, and where it was.

Why that matters

Reconstructing a radio incident means answering who said what, in what order. A recorder that stores only audio and a timestamp leaves you scrubbing through a timeline. One that logs PTT and talk group lets you pull the sequence directly.

Radio and telephony in one recorder

Most control rooms run both. A NexLog can capture VoIP and SIP telephony, analogue and digital lines alongside the radio network, so an incident that was over both radio and phone stays in one system.

CallTech supplies and supports NexLog recorders across Australia, as a physical appliance or as a virtual machine where the site would rather not add hardware.

What it does
Radio metadata, not just audio
PTT identity, talk group and position are logged with the recording, so a transmission is found by who sent it.
Radio and telephony together
Control rooms rarely run one or the other. A single NexLog captures both, so an incident is reconstructed from one place.
Certified with the major radio systems
Eventide has worked with the radio manufacturers directly, rather than treating radio as an afterthought on a telephony recorder.
Physical or virtual
A purpose-built Linux appliance where the site wants dedicated hardware, or a virtual machine where it does not.
