Call barring password

I just got a new Mobile Internet Plan.

Fido can only block incoming voice together with incoming SMS.

I would like to receive incoming SMS which is free but prevents from accidentally pick up a voice call.

There is a Call Barring network feature that can offer different options. One of the option is Call Barring - All incoming calls. But when I tried to activate it, it asked for Call Barring password.

What is the default Call Barring password in Fido??

Thanks
