Avaya Workplace (iPhone/Android/Mac/Windows) for IP Office should fully support Bridged Call Appearances. Including the ability to display multiple keys, support per-button-ring-control, place calls on hold, answer calls, place outgoing calls, show status of calls active/on hold from the users' physical phone and other softphones. It should work exactly as it does on a physical phone - and calls on hold/active on the softphone should be reflected accurately on other softphones and physical phones.
