Missed calls My Samsung D600 mobile only rings for a very short time and I miss calls - does anyone know how I can change the amount of rings

Enter the following code, replacing the question marks with your phone number, then press send (call) and it'll go for 30 seconds before switching to voicemail. **61*???????????*11*30# the 30 before the # is the number of seconds before it diverts to voicemail and you can set this in units of 5 up to a maximum of 30
