Viewers who vote via the free2call.tv website pay for their calls by listening to a 15-second online advert.With free2call the 35p 'diverted' call is paid for through sponsorship, with firms paying around £5,000 for 10,000 calls to the premium-rate lines. But with free2call they call a local-rate 03 number and avoid premium rates in return for listening to a 15-second advert. Calls are then diverted to an X Factor 09 premium-rate line with the cost paid by sponsors and advertisers.
So far viewers have been able to use free2call to vote on four of the six X Factor shows - it is only available if free2call.tv is able to find a sponsor.
The RSPCA sponsored 10,000 votes for around £5,000 in the fourth live show, which gave 3,500 votes to Danyl Johnson
