sorry for the delay haven't been on for a couple of days, to change Voda UK, try the following (it worked for me!).
You can manually change the length of ring time up to 30 seconds, firstly you need your mailbox number.. this can be found by dialing *#104# this will result in something like 44(string of digits, this is your mailbox number, ignore the letter after it.)
make a note of the numbers.
**61*+44mailboxnumber*10*30# and press send.
This should result in a message from the network and hopefully 15 extra seconds before the call switches to voicemail, you don't appear to be able to increase above the 30 seconds though.
