If you re sitting at your desk, your phone rings, just like normal. If you ve wandered off elsewhere within the office, you still get your calls because you take a mobile phone with you. If you re outside the office, a call to your business number is automatically routed to a cellular carrier, which routes the call to where you and your mobile phone are. In effect, your mobile phone behaves just like a cordless extension of your desk phone while you are on company premises. Calls within the office cost the same as they always have.
Calls connected to people outside the office carry the normal cellular fee.
Little else changes, either. You can program the phone so that you don t receive incoming calls when you leave the office. Or you can tell it that you only want to receive calls from certain key people. In other words, callers will only get past your voice mail if you want them to. But not your chin.
