Introduction to your BT Versatility system 
System description 
•  The BT Versatility is an Integrated Communications System supporting all your voice call 
needs and also provides an 'Integrated Data Solution' which allows multiple simultaneous 
Internet sessions and Voice over IP (VoIP) trunks. The VoIP trunks can be set up with a 
Broadband Voice Service Provider (such as BT Broadband Voice) or on a managed IP 
network. 
•  The  BT Versatility can accommodate up to  12 Analogue Lines, or 4 ISDN Basic Rate 
Accesses, or a combination of both, or 12 channels of ISDN Primary Rate with upto 4 
additional lines as backup, either PSTN or ISDN Basic Rate and up to 32 Extensions. 
•  The  BT Versatility is modular in construction.  It is upgraded by adding various system 
modules. 
•  The BT Versatility has a simple-to-use menu-driven interface. 
•  The BT Versatility is a hybrid PABX / key-system. 
•  The BT Versatility has an Optional Broadband Module providing seamless multiple Internet 
sessions. It also provides VoIP trunks which allows voice calls from extensions to be carried 
over a Broadband Voice Service Provider (such as BT Broadband Voice) or a managed IP 
network. 
•  The BT Versatility can operate with System Featurephones, standard Tone Telephones, or 
approved ISDN devices. 
•  Two Featurephone types are provided. The V8, which has 8 line keys, and the V16, which 
has 16 line keys. An Expansion Module can be used with the V16 Featurephone providing an 
additional 32 keys. 
•  The BT Versatility has remote access and maintenance capability. 
The BT Versatility’s modular design allows it to grow as you grow.  No matter what size system 
you start with, you can expand up to the maximum capacity.  The base system includes either two 
or four lines and allows up to eight extensions to be connected. The lines can be either Analogue 
,ISDN Basic Rate, a combination of both  or Primary Rate ISDN. 
The system Featurephone has a large display area that features an intuitive menu-driven 
interface.  Display Keys activate the facilities that are shown on the Display. It is not necessary to 
dial any feature codes when using the Featurephone.  This makes the system easy to use and 
saves you time. 
The BT Versatility is extremely flexible.  You have the choice of operating the system as either a 
key system: 
•  where all users have direct access to all lines for making and receiving calls  
•  as a PABX with all calls being answered by an operator console  
•  or as a hybrid combination of both   
You can choose to use system Featurephones or standard telephones at each extension, and you 
can change the set combination at any time.  A Door Intercom is available that can be 
programmed to ring any Extension, and a Doorstrike output is also provided.  A Long-line 
Extension, a Central Bell or external Music-on-Hold may also be used by installing an 'Options 
Module'. Alternatively external Music on Hold can be connected to the system via a Music on 
Hold Module connected to an extension port.
  
 
The BT Versatility is easy to install and maintain. BT can diagnose and programme your system 
remotely.
