Handset Features 38DHB0002UKCW – Issue 7 (10/03)
Using this Guide
This guide details the features that the 20DT handset supports by itself. The handset may
also be able to use other functions provided by the DECT and PBX telephone systems with
which it is working.
• INDeX DECT System
The 20DT can be used with GAP compatible DECT systems. When used with an INDeX
DECT system it can access several additional enhanced services (see "INDeX
Functions" on page 16).
• INDeX Telephone System
When used with an INDeX telephone system, the handset has a range of extra features
(see "INDeX Functions" on page 16). This guide describes how to use these features for
INDeX Software Release 9.2+. Ask your System Manager which Software Release
Level your INDeX system is using.
• Non-INDeX Systems
Refer to the manufacturer's instructions.
Within this guide, reference is made to the options in the Set-Up and Subscribing
procedures (see pages 7 and 12 respectively). Pressing the MENU key gains access to the
menu structure for these options. Two versions are available, dependant upon the software
issue of the 20DT.
To determine which menu structure you have:
• Dial *99982*.
• Press and the display will show the PCS level (on the second line).
• If the PCS level is 4K or greater it means that you have the latest software
available to you
Both of these versions are shown on page 5. Throughout this guide, the procedures
detailed are for the latest version of the software.

Subscribing 38DHB0002UKCW – Issue 7 (10/03)
Subscribing
Introduction
For DECT handsets to be connected to a DECT system they have to go through a process
called ‘subscription’.
Logging On:
The 20DT can subscribe to any one of four DECT systems. However, although the 20DT
can subscribe to up to four systems, it can only be logged onto one of those systems at any
one time.
Multi Site Roaming
A 20DT can, across up to four sites linked by INDeX net, be used by the same user.
Hence, when moving between sites the 20DT user will be automatically able to
make/receive calls and use all of the 20DT functions. To activate this facility the following
actions are required:
• At each INDeX site, the 20DT must be allocated to a Mobile Users group (provided
by your system manager).
• At each INDeX site, the 20DT must be subscribed to the system (see below).
• The 20DT must be set to Auto when setting up for "Switching Between Systems"
(see page 14). This only needs to be done once at any site.
Hot Desking
A 20DT can be used as a Hot Desk phone. Hot Desk users can log onto multiple sites,
linked by INDeX net. However, the Hot Desk user must use a 20DT handset that remains
on a particular site. To activate this facility the following actions are required:
• At each INDeX site, the 20DT must subscribe to the system (see below).
• At each INDeX site, each 20DT's number must be set as a Hot Desk Mobile Users
type (provided by your system manager).
• At each 20DT that is being used as a Hot desk phone must be allocated (by your
System Manager) two numbers. One to log on with and one to log off with (see
below).

system to log on to. Alternatively, if your 20DT has been registered on other remote (at
other locations) systems, you can select the Auto Subscribe option (see page 13) on your
20DT. Hence, when you move between the two locations your 20DT will automatically
subscribe itself to the new system.
Auto Subscribing Handsets
When moving between two locations, both equipped with IP Office and Compact DECT
systems, you can set a handset to automatically subscribe to the other DECT system
provided that the handset at been registered on both systems (consult your system
