A telecommunications system includes a cellular telephone equipped with a global positioning utility for receiving global positioning samples. The cellular telephone periodically transmits received samples to a location client application running on a computer that also includes a unified communication client suite. The location client application derives a location confidence factor from the samples. The confidence factor is provided to a presence and availability service. Incoming calls and/or notifications can be routed to a user based on the confidence factor.
