Avaya 5400 Series Handset is a spare or replacement handset designed for compatible Avaya 5400 Series digital telephones. It provides a practical replacement when the original handset becomes worn, damaged, lost, or otherwise needs to be replaced while allowing the existing telephone to remain in service.
This replacement handset is designed for several commonly used models in the Avaya 5400 Series, including the 5402, 5410, and 5420 digital telephones.
