Yes, on all phones you can log in with your own internal number (e.g. 201) and your own PIN number. It takes 10 seconds and you can start calling immediately. This applies to all phones, brands and models that we supply (including conference phones). By the way, if you do not have a flexi-place, you only have to log in once and you remain logged in. Also the next day, even with a power failure or storm Ciara. You are only logged out when you want to be.
