Providing improved post-dial delay at an originating terminal
Abstract:
To provide expedited ringback at an originating terminal, a call request is sent from the originating terminal to a destination device over an Internet Protocol (IP) network. Local resource reservation is performed by the originating terminal after sending the call request. A first message is received by the originating terminal prior to the originating terminal sending a second message indicating that local resource reservation has been performed, the first message for indicating that alerting is being performed at the destination device. In response to receiving the first message and determining that the local resource reservation has been performed, a ringback indicator is generated by the originating terminal.
