Welcome to the forums
I'm sorry that you're having issues with the voicemail. If you're unable to change the voicemail rings by entering the keys, please give us a call on 789 or 0345 6000 789 and we'll get this sorted.
We may need to raise an IT ticket to get this sorted.
Let me know how you get on.
