I press and hold '1' and is giving the following prompts:
"To leave a message dial the 10 digit mailbox number for the person you are calling.. If you have a mailbox number, please press #"
I dial my number and it says: "Could not find a mailbox for that number.."
I've tried using the access number in my options>call management>Voice mail
And i've tried using my own 10 digit number..
