Choose how many seconds you allow the phone to ring before the voicemail picks up. The standard time is set for 20 seconds but you can change this duration: if you want your voicemail to pick up after 5 seconds you have to type **61*+32490468787**5# on your phone keyboard and confirm with the dial button. Instead of 5 seconds you can also choose between 10, 15, 20, 25 or 30 seconds. If you want to do this you have to change the 5 in the instruction with the number of seconds you want.
