Abstract
A system and method for voice-activated dialing using implicit and explicit trunks including receiving a call from the user telephone and establishing a first connection. In response to establishing the first connection, a second connection may be established over the implicit trunk. In response to establishing the second connection, a third connection may be initiated. In response to the user telephone sending a keyword, the implicit trunk may be disconnected and the call may be connected via the explicit trunk. If a spoken number is received, then the spoken number may be translated into a computer readable telephone number. Alternatively, if a dialed telephone number is received from the user telephone, the telephone number may be used to route the call. In response to receiving the telephone number, the explicit trunk may be disconnected and the call from the user telephone may be routed to the received telephone number.
