<P> Clients are attracted to 084 and 087 numbers because per minute revenue is generated for them from each call, and call queuing is permitted . Call centres may generate very high revenue from high call volumes . Questions have been asked in the British House of Commons about how much money the UK government is receiving from call queuing on non-geographic numbers . </P> <P> There is increasing consumer opposition to non-geographic numbers . This is partly due to revenue sharing concerns and partly due to these calls not being eligible for use within inclusive minutes . Whilst a national or regional business may want a single contact number that is not tied to a location, there seems little sense in a small trader covering a town, or at most a county, having a non-geographic number for their single telephone line . Businesses are attracted to using 084 numbers as many of the sellers of NGNs assert that callers are paying only a "local rate" call . </P> <P> Consumers are aware that they are being charged for time spent waiting for their call to be answered . (Even more of the public is aware of the huge costs of 09 Premium rate numbers, where prices have to be clearly indicated, and on which call queuing is specifically prohibited .) There has been increasing media coverage which has raised awareness of this . </P> <P> During debates in the House of Commons, a number of Members of Parliament have criticised the use of 0845 numbers to provide access to government services, such as at the Department for Work and Pensions (DWP). It is objected that taxpayers are already financing government services via taxation, and in the specific case of DWP that many callers are benefit claimants without much money . The DWP is in the process of migrating from 0845 numbers to 0800 or 03 numbers . The Department of Health undertook a public consultation on banning 084 numbers in NHS services and amended GP contracts in 2010 to ban their use . </P>
