Expansion beyond 8 extensions - BT Versatility Trade Tips from ToneTel Telecom
If you need to expand your Versatility phone system beyond 8 extensions (or beyond 4 analogue PSTN or 4 ISDN2e channels) then firstly you need to fit the Expansion backplane.  A Ports module is required to expand the extension & line ports.
Each Ports module is equipped with 8 hybrid extension ports and two slots for trunk cards.  So with additional PSTN line or ISDN2e Modules an expanded Versatility system with a single ports module provides up to 16 extensions and 8 lines.
The system extension & trunk limits are currently 32 extensions and 8 lines (this limit may be expanded to 12 in the future), unless the PRI ISDN30e module is fitted.

Department/Group Mailboxes - BT Versatility Trade Tips from ToneTel Telecom
The Versatility Voicemail module can provide personal and group (shared) mailboxes + a central system answering machine.
One major limitation is that the groups and extensions all have to share the same divert on no-answer timer for forwarding to voicemail, though the system answer machine has its own.

What is the Versatility - BT Versatility Trade Tips from ToneTel Telecom
The Versatility system is manufactured for BT by Lake Communications (Eire), the original product is known as the 'OfficeLink' and is also known under many other names around the world.
The Versatility system is only available for new sales direct from BT, but there is a large second-user market with most parts and add-ons available.  The BT Versatility is a typical Lake system (manufacturers of the Revelation, Inspiration & Pathway) with its user-friendly menu-driven interface and design.  It would be classed as a basic low-cost digital system as though it has some great features it cannot be compared in the same class as other manufacturer systems such as NEC, Avaya, Mitel etc.
It is sized to suit small offices with just a few extensions up to 32 users.

Firmware Compatibility - BT Versatility Trade Tips from ToneTel Telecom
An important fact about the Versatility system is firmware issues and compatibility.
Many an engineer and independent dealer has fallen foul when upgrading a system or adding voicemail etc, many modules are firmware level dependant and systems with earlier firmware version had quite a few bugs which can be a problem especially when systems are purchased from auction sites etc.
Generally the firmware flash files are not available outside BT but a few independent companies have been able to obtain them and ToneTel Telecom can upgrade systems to the newest VoIP compliant 719 firmware.
Below is a general guide from BT documentation and site experience of firmware compatibility:
 
Mini External Music-on-Hold module - Rev 473 and above.
Broadband Voice Module (inc VoIP) - Rev 677 and above.
PRI ISDN30e Module - Rev 567 and above.
8-Port Advanced Voicemail module - Rev 567 and above (newer 40-port motherboard also required).
2 & 4-Port Voicemail Modules - Problems noted dependant on module revision when system is on older firmware (i.e. 2/3 or 4).
 
The system firmware version is displayed briefly on start-up, can be obtained from system telephone programming or via the Ovida PC management utility (engineering version only).

Adding a Mobile GSM Gateway - BT Versatility Trade Tips from ToneTel Telecom
A Mobile GSM Gateway (Premicell) can be easily connected to the Versatility system as long has it has a spare PSTN or ISDN trunk port (dependant on the Gateway type to be connected).
Additionally the Versatility routing tables can be programmed to route necessary numbers (such as 07) automatically to the Gateway with optional override codes for the extension users.  Routing can be on a first-choice or exclusive basis.

Least Cost Routing - BT Versatility Trade Tips from ToneTel Telecom
Unlike many BT branded phone systems the Versatility does have LCR (Least Cost Routing) tables.  One limitation however is that for most area codes, local calls cannot be routed with a Carrier prefix and the local area (STD) code.
The routing tables can be used for the following scenarios:
Standard LCR - to prefix a telephone number with a carrier access code.
GSM Mobile Gateway - to route 07 mobile calls
VoIP Gateway - to route required numbers or as a preferred outgoing route.
Preferred Line - as an example in a small office with 2 lines (1 is for a fax), customer may want all outgoing calls to use the fax line as first choice route to leave the voice line free for incoming sales calls.

'Commission System' message - BT Versatility Trade Tips from ToneTel Telecom
The 'Commission System' message will normally be displayed on Extension 20 (first extension) as a reminder to BT installation engineers, it has no impact on the operation of the system.
It will normally appear when the system is factory defaulted etc.
ToneTel Telecom can easily remove this message by calling the system into the BT RACE system.

Lines not releasing - BT Versatility Trade Tips from ToneTel Telecom
A common problem with PSTN line connections seen on some installations (including a lot of BT ones) is that the lines take a long time to release after a call is ended.
This is a simple programming mismatch between the Versatility configuration settings and the BT lines connected, ToneTel Telecom can easily resolve this problem with a configuration settings change.

Diversion on No Answer - BT Versatility Trade Tips from ToneTel Telecom
One common complaint about the Versatility system is that there is only a single Diversion on no-answer timer which is shared by all extensions and groups for general call forwarding and forwarding to voicemail.  This can cause configuration difficulties when arranging forwarding to voicemail for extensions or for groups which need to reroute to a voice mailbox on no-answer.
The system answer machine does have its own separate timer.
