Avaya IP Office 8.1 Product Description page 158

The new DECT R4 handsets will work with the legacy IP DECT system. Nevertheless not all features available
with the 3701 and 3711 handsets will be available on the DECT R4 handsets as well. An (incomplete) list of
working features is:
· Subscription with PARK.
· Basic Call.
· Display Messages (with some limitations, e.g. truncation at end of line).
· Handover.
· Roaming.
· R-Key Handling (Enquiry call, Conference, ...).
· Feature Access Codes.
· Distinguish between internal/external calls.
· DTMF during call.
· Local call log (calling party numbers are transmitted).
· Local time and date.
Features already known to be not working with DECT R4 handsets and the legacy IP DECT system are
· Access of external directory (e.g. LDAP).
· Get time and date from the system.
· WML (WAP access).
· SMS/Messaging (not a feature of the legacy IP DECT system).
Generally it is highly recommended to do a sample installation with one handset first before rolling out a larger
set of DECT R4 handsets on a legacy IP DECT system.
