Abstract
A dispatch based call system configured to contact a call center using a single unique name or number. Multiple users are able to simultaneously dispatch the single generic call center number and communicate with a unique end station or individual at the call center. A user, or subscriber unit, when dispatching a call communicates initially with the service provider infrastructure. The infrastructure then establishes communication with the call center. The call center determines the identifier of an available end station and the subscriber is subsequently connected to the available end station.
