Thanks for the pointer to the BT info. Apologies for lack of clarity: it wasn't at all a rhetorical question. I really would like to understand the technology.
If DWP have the BT advanced option, or something similar from another provider, what happens?
(a) Calls to DWP's 0845 numbers are first translated to primary real numbers (say in Newcastle), and then re-routed according to time-of-day, number of calls currently queuing at Newcastle, or whatever; or
(b) Every exchange in the UK (and wherever calls first arrive from abroad?) knows whether to route them to Newcastle or somewhere else according to time of day etc.
(b) seems unlikely, to me. But if (a) is true, then, in principle, couldn't DWP make known the real primary numbers? And wouldn't calls to them be re-routed just the same? Or would the provider of DWP's 0845 service object, because they would lose their cut of the 0845 call charges?
