comms-brokers' NGN (non-geographic number) system allows businesses the ability to route incoming calls to multiple landline and/or mobile numbers, and also deliver voicemail and fax to email services.

These non geographic numbers are not attached to any geographical area in the UK. Rather, they can be pointed to any existing landline or mobile number in UK and even routed internationally. This is possible because they have prefix which does not belong to a specific geographical destination of the call. They have gained significant importance among large and small businesses, as they offer a wide range of facilities which include:

• Diverting calls to a particular destination/ phone number.
• Set interactive voice response for the callers. Once the caller has made a choice by pressing a specific number on their phone, they can be directed as the business chooses - to individual members of staff, hunt groups or voicemail.
• Offer fax to email facility which converts an incoming fax into a digital format, which is then sent to client through email. This makes it possible to access fax messages without a fax machine, anywhere in the world.
• They are low cost and offer easy and effective communication.

Non-geographic numbers come in a variety of number ranges, including:

• 0800 - These are free for the callers, and the company that installs them pays for the incoming calls. They are a highly effective advertising and marketing tool, as they invite prospective customers to call for free. They send a positive message to customers around the world, helping firms to build a respectable image and customer base.
• 0845 and 0844: With these number ranges, the caller has to pay "local" call rates. Local rates are charged to the caller irrespective of where from UK the call is being made. These numbers help advertise a firm's products and services nationally, and create a very professionals image for the business.
• 0871: Here, the caller is charged at "national" rates. They too help create a national presence for firms.
