I have finally got a reply from BBC
'Thank you for your e-mail regarding 'Strictly Come Dancing'.
I am sorry that you had difficulties getting trough to vote for Louisa and Vincent on Saturday 9 December 2006. I have fully registered your comments onto our daily log.This internal document will be made available to the 'Strictly Come Dancing' production team and Senior BBC Management.
The phone lines for this service all work off of the same mass access voting platform. This platform is the largest in the UK and allows in excess of 200,000 calls per minute to be counted. Therefore, if more than the number of calls are being made at one time, then some people will get the engaged tone. The lines were tested on Saturday and all was working well - if lines were engaged it was possible to get through after a few seconds.
If the lines are busy for one contestant, they will have been busy for all contestants involved in the vote. The voting platform is not biased in favour of one contestant or another.
The voting platform works on initially recognising the first 9 digits of the dialled telephone number. The numbers consists of 11 digits and only the last two indicate which contestant is which. The rest of the number is identical for everyone. These first 9 digits tell the local telephone exchange you dial into when you call, that the number is one allocated to the mass access voting platform. It then tries to route the call to that voting platform. Once it reaches the platform, the platform then finally recognises the final two digits of the number and counts a vote for that particular contestant. If the phone lines are engaged, it is happening at the first part of the call, at the local exchanges. At this point the system (the last two digits) it doesn't recognise which contestant is which - it only looks at whether it can get the call to the platform. Therefore it is not possible for the platform to be biased and it is not possible to prevent calls to any one particular number over another.
Always in these votes, the percentage of callers who do get through and have their votes registered, reflect the opinions of those people trying to vote. It's been proven over and over again in terms of percentages.
