Today I was bored so I thought I'd have a look on Wikipedia..
I stumbled across Mobile Number Porting and was suprised to read the following:

Which got me wondering. As we, in the UK, seem to be using this backwards way of porting numbers, what happens when you've had your number for many years and crossed many networks?
For example, my number originated from T-Mobile, then I ported to O2, then to Orange. Now according to that article, whilst I was with O2, my calls were still being routed via T-Mobile. Now I'm on Orange, does that mean my calls now go Orange > O2 > T-Mobile > wherever I'm calling?
Seems to be a hell of a waste of money and network capacity!
Anybody any thoughts? Is that article correct?
I stumbled across Mobile Number Porting and was suprised to read the following:
A significant technical aspect of MNP is related to the routing of calls or mobile messages (SMS, MMS) to a number once it has been ported. There are various flavours of call routing implementation across the globe but the international and European best practice is via the use of a central database (CDB) of ported numbers. Network operators generally hold local copies of CDB and query it to find out which network to send a call to. This is also known as All Call Query (ACQ) and is highly efficient and scalable. Majority of the established and upcoming MNP systems across the world are based on this ACQ/CDB method of call routing. One of the very few countries to not use ACQ/CDB is the UK where calls to a number once it has been ported are still routed via the Donor network. This is also known as 'Indirect Routing' and is highly inefficient as it is wasteful of transmission and switching capacity. Because of its Donor dependent nature, Indirect Routing also means that if the Donor network develops a fault or goes out of business, the customers who have ported out of that network will lose incoming calls to their numbers.
