Quick Reference Troubleshooting Guide
Avaya EHS Adapters
Scope
This document is intended to provide basic guidelines for technical support staff answering support
questions from customers experiencing difficulties with the Avaya EHS adapters.
Requirements
Telephones
Table 1 highlights the different phones supported by each EHS adapter. For some phones
restrictions apply on the telephone firmware version, switch type etc. These restrictions are also
listed. It is very important to note that the Avaya Model 2420 phone only works reliably with
Electronic Hook Switch when it is connected to an IP switch. Older digital switches are not
guaranteed to work.
