About CEHS-AV 05 - Avaya Electronic Hook Switch Cable (1000742)

The EPOS CEHS-AV 05 is an electronic hook switch cable that connects your EPOS wireless headset to a compatible Avaya desk phone. It lets you answer and end calls from your headset, even when you're away from your desk, so there's no need for a mechanical handset lifter. This model is end of life and available while stocks last.

Why Choose This Product?

Our Telrexperts recommend the CEHS-AV 05 for anyone running an EPOS wireless headset on an older Avaya desk phone. It's a small accessory that makes a big difference to how freely you can move during calls. Just note that Avaya system software version 1.8 or higher is required.
