Some telephones offer the choice of increasing the volume of the call to help you hear the person you are speaking to more clearly. If your phone has a hands-free button you should also be able to turn up the volume of these calls. Some phones also include a separate amplification button which means you can boost the volume even more (British Telecommunications (BT) 2008).
Workplace solutions and adjustments
Setting telephone volume controls to a suitable level for an individual may assist people who are hard of hearing to be able to use a telephone for work purposes (Job Accommodation Network 2007).
