Business Phone Lines - ISDN30e, ISDN2e, Analogue and SIP Trunks

Spitfire Business Phone Line Rental

Spitfire’s Phone Line Rental portfolio includes services provided by Openreach (a BT Group Company), that have equivalence with all BT Retail products. This allows us to provide our clients with a genuine one stop solution to their telephone service requirements.

Our relationship with Openreach is second to none, as is our experience in delivering and managing customers phone lines on an on-going basis.

Some of the major reasons for transferring line rental to Spitfire are as follows:

• All management, provision of new lines, cancellation of old lines, moves and changes are carried out by Spitfire - you never need to call a BT Retail call centre.
• Clients benefit from Spitfire advice and consultancy from a specific account manager.
• Free audit of current telephone billing and rental charges.
• A clear and easy to understand single billing solution – all sites, telephone numbers, usage descriptions, rental charges, call charges, broadband and mobile costs on one monthly bill.
• No transfer charges.
• All transfers are handled from start to finish by Spitfire. This is an administrative change – no site visits by engineers required.
• Existing BT Retail and other numbers retained – including when moving sites.
• Full management when moving sites – how to retain your phone number etc.

ISDN30e

ISDN30e is the premium Digital business line service – available from 8 channels (lines) up to 30 on a single bearer cable, and with the ability to use multiple bearers, ISDN30e is the most flexible digital business phone line service available.

ISDN stands for Integrated Services Digital Network, the ‘e’ on the end denotes the European standard ISDN service rather than the older DASII variant that was a UK standard. ISDN has been available in the UK since 1992.

ISDN30e is ideal for customers requiring any number of lines from 8 upwards, it uses Direct Dial In (DDI) numbers allowing individual DDI numbers to be used for individuals, departments and marketing purposes.

Key features include:

• Available from 8 channels upwards on one connection.
• Good value DDI numbers in blocks of 10.
• Can port an existing single number as an SNDDI (Single Number DDI).
• Up to 5 DDI ranges (an SNDDI counts as a range).
• Spitfire generally supply ISDN30e with Service Level 4 as standard for a 6 hour fault clearance time 24 x 7.
• You can increase or decrease the number of channels very easily, in single channel increments.

ISDN2e

ISDN2e is a smaller Digital business line service, that comes with 2 channels on one connection, with the ability to line multiple connections together, each with its own connection box (NTE), but with DDI numbers across all linked connections.

The use of DDI numbers is exactly the same as with ISDN30e. ISDN2e can also be used with stand alone equipment such as Video Conferencing, although this is now usually done via an IP (Internet Protocol) connection.

Key features include:

• Available in multiples of 2 channels as pairs of channels.
• As ISDN30e – DDI numbers and moving an existing analogue line number are both options.
• Suitable for up to 8 digital lines (4 x 2 channel connections).

Analogue Lines

Analogue lines are the most basic form of phone lines, having been in use for over 100 years. Analogue lines are a PSTN service rather than ISDN (Public Switched Telephone Network), and are still widely used for a variety of purposes such as alarm lines, an ADSL bearer line, PDQ machines, or just as a simple phone line – most residential lines are single analogue lines.

There are two types of analogue line available – Basic lines and Premium lines. Please see the Service Level Agreement for details on the differences in fault repair times.

Spitfire will always recommend and use Premium lines – when comparing costs please be aware that many of our competitors moved every single Business line to become Basic lines, with the corresponding reduction in service.

Key features of analogue lines include:

• Available as single Direct Exchange Lines (DELs) for use with alarm, PDQ, ADSL or Fax.
• Also available as Multi-Lines on one number for business use (no DDIs etc).
• Wide range of Special Services available such as Call Minder, Call Divert etc.

SIP Trunk Lines

Over 60% of our new business phone lines use SIP Trunking – this is a business quality VoIP (Voice over IP) service.

Spitfire have been supplying SIP Trunk services for over 6 years and are one of the UK’s leading suppliers.

SIP Trunks allow savings of up to 70% compared with ISDN30e/ISDN2e or analogue lines and as importantly also offer significantly enhanced business features – especially around resilience and back up services.

Key Features of Spitfire SIP Trunks include:

• Low cost business phone services.
• Unlimited DDI numbers.
• Port existing numbers – and deliver to anywhere in the UK.
• Not restricted to your geographic location, i.e. have a Birmingham number in London.
• The ability to forward calls to other numbers in the event of a line failure – i.e. DDI numbers can be forwarded to individual mobiles.
• SIP Trunks can connect to multiple sites.
