I plugged in our koodo landline today. We still had bell service when I did this. We can dial out, but cannot receive calls, phone won't ring either. I tried plugging in a base, then a standard phone with the same results
The port does not complete all at once. Your outgoing calls will work before your old number gets ported from Bell. Keep a phone device plugged into your wall jack until the port completes, at which time your new WHP will ring when your old number is called.
