I have just purchased call barring for my landline, and have set to bar all outgoing calls .
In the Call Barring instructions I need a 4 digit pin to remove the barring option and allow calls.
I need to know what the pin is (so I can manage the option). Also change it if it is something obvious like 1111 or 1234, and my guests know this and start making expensive calls.
How do I find out what the pin is?
How do I change the pin?
THANKS
