On the SL1100 and SV9100, analog lines, I can directly access a trunk by dialing #9 and the 3 digit trunk number. But only if I have the trunks assigned to a key. So it sort of defeats the purpose of doing direct access with a service code, when all you have to do is press the right button.

Is there a way to do direct trunk access without having keys assigned for the trunks?

Thanks.
