I followed this document to change the duration my phone rings for.
I want it to ring ideally for 45 seconds like it does on other networks but 30 is fine.
When I change it, it won't allow me to go past 20 seconds, even though the document says 30 seconds is max.
Is there a way of extending the duration other than sending the code, I used the menu on my phone and that doesn't even give the duration setting.
Thanks
