Here's the most recent version of the Gentner (now Comrex) Digital Hybrid series of broadcast POTS phone line interfaces. The unit sends the output from your console to line (note that the use of a mix-minus/clean feed signal is required) and presents the caller audio on one of your fader channels for the DJ to control just like any other audio source. This late model unit offers both AES/EBU digital and balanced analog XLR connections, so you can interface to digtal and/or analog channels on your console. Item has been tested and found to operate as expected. The unit has the ability to auto-answer calls if required. The photos show the actual item for sale.

Manufacturer's Product Overview
With the variety of phone systems in the world today, it is becoming increasingly difficult to have all callers sound the same on-air. To help bring uniformity and high quality sound to a broadcast talk show environment, we have created the DH30.
The DH30 provides a high quality interface between a standard telephone line and your audio equipment. Designed with both AES/EBU and analog inputs and outputs, the DH30 can interface with the latest digital and analog consoles. To ensure quality sound in studios that have open speakers and microphones, the DH30 was created with an acoustic echo cancellation feature.
The DH30's digital signal processing (DSP) has multiple adjustable parameters to provide you with the best send and caller audio signals. New audio processing features such as the compressor and downward expander functions ensure that the best audio reaches your audience. All audio processing features are programmable via the front panel controls. For the deepest, most reliable hybrid null, and the best quality caller audio for your application, the DH30 is the answer.
Easy to use and install, the DH30 has simple front panel controls and remote control capability. These controls put the On, Off, Rec, and Cue functions right at your fingertips. The DH30 also includes a 2W monitor amp with volume controls right on the front panel. The Rec function sends a start/stop signal to your external recording device. The Cue function allows you to control which audio signal should be sent to the caller, allowing you to switch from the Send input to the Cue input at the touch of a button.
