Developed specifically to meet the needs of small and midsize businesses, the Avaya 5400 Series Digital Telephones incorporate sleek design, improved ergonomics, flexibility, and enterprise-class voice quality. These two-wire digital phones come in three models, all of which feature paperless button labels, local call log, and speed-dial directories.

This phone is similar in physical appearance and functions to the 2410. However the 5410 phone is only supported on IP Office.
