Avaya 4400 Series Handset is a spare or replacement handset designed for compatible Avaya 4400 Series digital telephones. It provides a practical solution when an original handset becomes worn, damaged, lost, or otherwise needs replacement while allowing the existing telephone to remain in service.
Designed for use across several models in the Avaya 4400 telephone family, this replacement handset can help extend the useful life of existing business telephone equipment. Replacing only the handset is often more practical than replacing an otherwise functional telephone, particularly for organizations maintaining established Avaya communications systems.
