RAILWAY HANDSET ERMETRIS
RAILWAY HANDSET ERMETRIS 2

SIP-VOIP RAILWAY HANDSET EN50155

The Ermetris VOIP Railway Handset has been developed and manufactured with the aim to create a device that meets the demanding standards required in the railway field.  Low profile: the handset’s reduced depth facilitates its assembling within electrical wall cabinets with doors.

Magnetic fastening to the cradle: the lack of release buttons allows the handset to be easily used also without specific instructions or prior knowledge and experience.

Rugged and easy to install: the handset is built with robust materials and all parts are secured with screws.

The cradle does not need to be disassembled to be fastened to the supporting panel.  Excellent sound quality: the transducers and their position within the handset have been carefully selected in order to obtain maximum audio performance. Various options available: it is not one single product but a range of products.

In fact, the handset can be customised according to different needs and it can be equipped with either a dynamic or electret microphone, with different types of connectors, and with a speaker in the cradle.

Thanks to the SIP standard VOIP communication the customer can have a ready to use device with no need of software development.

The VOIP Railway Handset has also the option to be a simple SIP server and not only client.
