Following the instructions provided by Panasonic Tech Support, the TDA50can be configured to "somewhat" comply with Kari's Law. I have set up a TDA 50 system that used to have auto CO hunting and will no longer access an outside line when the handset is lifted. When a line button is pressed, access is not allowed. I assume that it is looking at the digits being dialed, before it selects a trunk group and dials out. The customer does not like this AT ALL. Old habits, you know. I am wondering if auto co hunt at all extensions, is considered compliant????
