How can I lengthen the number of rings before the answerphone kicks in

I followed 'To activate= **61*901*11* number of seconds #

and I get

'Error performing request

Unknown Error

Setting Registration Failed

Voice Call Forward

When Unanswered'

Thank you for your help

Try turning off wifi first or dial ##002# which will cancel all diverts.

Thank you, I will wait for a week before I try that because it is most important that I still receive a message if I miss a call at the present time.

I will accept it as a solution in the mean time!

To get notified you need to turn on call alert as described in this guide Guide: All you need to know about O2 Voicemail 901

##002# does not work

[TimandTom]

Sorry, nothing works

Did you turn off wifi first?
