In the simplest case, the 0800 (Non Geographic Number or NGN) is translated into a regular UK geographic number (UK telephone numbers starting with 01 or 02) these are generally associated with a telephone line (landline number). This number is then routed by the telephone exchange in the normal way so when a caller dials the 0800 Phone Number the regular number rings. This is called Standard Routing.
An alternative is not to translate the 0800 Phone Number to another number directly but to route the caller to phone call services platform which provides features including routing by time of day, location of caller, day of week, capacity, etc. to be employed. For example:
This is called Intelligent routing.
Combining your 0800 telephone number with a virtual switchboard and intelligent routing will make your clients actively want to phone you. Instead of finishing up with a press button switchboard or explaining their problem to two or three people, their call can be automatically routed to the person or department they normally deal with. In a win-win situation, not only will you be receiving 3ppm for every call and saving administration costs, your clients will be happy too.
Standard Routing Service with 0800 numbers (Number Direct).
Your 0800 number "sits" on top of your UK landline number only. When customers dial your 0800 number they are redirected to your own landline. This does not affect your UK landline number in any way. 0800 numbers will only work diverting to UK landline numbers they will not work diverting to other number types such as mobile or international.
