The headset telephone is a two-piece unit in and of itself, relying on just a standard telephone jack for power and connectivity. This simple plug and go design makes life easier for the call centre and its workers, while remaining one of the most cost effective solutions for the inventory and equipment budget. The specific features available with headset telephone models will vary depending on the manufacturer.

The headset telephone includes a box unit which is small and can be mounted to a desk area or carried on the users person. This box houses the number key pad, and is usually equipped with hold, flash, conference, and call lights, depending upon the model chosen. Most headset telephone units allow incoming calls to be announced with a simple lighted flash pattern rather than a potentially disturbing ring tone, improving privacy and call quality.

Unlike the standard headset system, the headset telephone can be controlled with a visible panel. Fumbling fingers are taken out of the equation, as all commands and prompts can be addressed through the small, convenient telephone box. These units can be muted, allowing the user to set indicator lights for incoming or waiting calls.

Most headset telephone systems are equipped with information storage chips which will allow for call monitoring and evaluation by superiors during any time of the working day, or whenever the need presents. These phones are usually available with an indicator light showing when the line is active, as well, helping the user to determine whether the call has been successfully ended before carrying on with other conversations.

Volume control on the standard call centre headset can a bit of a pain, but the headset telephone offers easy controls that the user can see and adjust easily. Most models are offered with a headset stand for ease of storage and increased functionality. Another plus for the headset telephone user is that most headset units are fully convertible from over the ear to headband, and can also be swiveled for use on either side of the head, increasing comfort and productivity.
