The BT Inspiration is available in 6, 12 and 18 extension configurations. It is possible to expand each system up to the maximum 6 lines, 18 extensions configuration by installing expansion modules in the central control unit.

It can be configured as an analogue system, connected to standard telephone lines, or an ISDN system connected to ISDN2 lines. It can also be configured as a mixed system connected to both analogue and ISDN lines.

If you choose a digital BT Inspiration system package connected to ISDN2 lines, you can take advantage of network features such as Direct Dialling In.

BT Inspiration is also compatible with:
Answer machines.
Point of Sale Equipment.
ISDN devices.

As well as the features that you would expect from a telephone system such as the ability to transfer calls internally, provide music/ tone on hold and speed dialling, BT Inspiration also has features normally only associated with large telephone systems. 

Some of the most exciting features offered by the BT Inspiration are its external transfer and external divert facilities. 

Now, transferring calls to any outside telephone number is simplicity itself. With divert, calls can go directly to any external number of your choosing, automatically. So whether you're working at home, in another department or on-site via your mobile, BT Inspiration takes the office to wherever you are. 

Voicemail is a highly featured cost effective solution for the small business enabling customers to never lose that vital or confidential business call, they can be open for business 24 hours a day. The system can also be used as an internal messaging system ensuring that messages and ideas are never lost.

The Auto Attendant feature allows callers to ring directly through to an extension, provided that they know the extension number of the person they wish to contact. This service is available only when a voicemail is fitted.

Call Manager offers customers the option of using their PC to control their Featurephone and generate customer records for all calls made and received from that extension.

Call Logging Interface 
The Call Logging Interface allows you to connect to a serial printer or a PC enabling time, date and duration details of incoming and outgoing calls to be recorded helping to monitor and control costs. Call logging does not record call costs. 

Door Intercom 
The Door Intercom is an entry phone, which can be connected to the BT Inspiration and allows you to control entry to your premises without leaving the desk.

Battery Back Up 
An optional Battery back up unit can be installed which provides full operation for at least one hour in the event of a mains power failure. Replacement batteries are widely available. 

Optima is available as a single receiver or as the Optima Duo with two receivers. Where customers are working in noisy environments we recommend the Optima Duo as the binaural design cuts out distracting background noise.

Central Bell 
A central bell connection is provided on all units. A bell can be wired to the connector and it can be programmed to ring for incoming calls in day or night mode or both.

BT Inspiration Advantage+ is the complete voice and data communications system that is ideal for all businesses, including branch outlets such as, pub chains, petrol station forecourts and retail outlets. 

The BT Inspiration Advantage+ package supports 1 digital line, 2 analogue lines, 12 extensions, desktop ISDN and a router to give fast access to the internet and company intranets. Also, with the benefit of system passwords, security is enhanced to prevent tampering and fraud. 

The BT Inspiration Advantage+ can grow to a maximum of 3 digital lines or 6 analogue lines (or a combination of both) and 18 extensions. 

The BT Inspiration Advantage+ has the same wide range of features as the BT Inspiration.

In the event of a power cut you will still have full analogue service.

The Featurephone makes it much easier to use due to its large graphic display guiding the customer through the use of the various features. Each BT Inspiration system MUST be equipped with at least one Featurephone for system programming.
