How do I change the number of seconds before voicemail picks up a call?
I have tried **61*901*11NN# and then pressing call and also sending via text without success. Voicemail still only allows 15 seconds. (also tried **61*901*NN# and sent that both as a call and also text). NN = number of seconds required and I tried 30.

Check the physical phone settings are not overwriting them on sending and have a look at this guide here Guide: All you need to know about O2 Voicemail 901
