Abstract: A contact server receives a request to initiate an out-bound call to a recipient device. The request identifies the caller device by a cellular network phone number. The contact server establishes a communication link with the caller device and determines its associated data network phone number. The contact server establishes a communication link with the recipient device, indicating that the data network phone number of the caller device is the source of call, and bridges the two links. The contact server may receive a request for an in-bound call to a recipient device. The request identifies the recipient device by a data network phone number. The contact server establishes a communication link with the caller device and determines a cellular network phone number associated with the recipient device. The contact server establishes a communication link with the recipient device using its cellular network phone number and bridges the two links.

Abstract: A call server includes a network interface for connecting the call server to a packet-based network within a telecommunications network. The call server establishes a first connection with a calling party terminal and a second connection with a called party terminal via the packet-based network. The call server then joins the first connection with the second connection to establish communication between the calling party terminal and the called party terminal. The call server may park the second connection when the first connection is terminated or vice-versa and establish a new connection with the calling party terminal via the packet-based network if the first connection was terminated or vice versa. The call server may join the new connection with the first or second connection to reestablish communication between the calling party terminal and the called party terminal.

Abstract: Systems, devices and methods for implementing a hold-call-back feature in a telecommunications network. A first connection is established between a call server and a first terminal via a packet-based network and a second connection is established between the call server and a second terminal via the packet-based network. The packet-based network comprises at least a segment of the telecommunications network. The call server then joins the first connection with the second connection to establish communication between the first terminal and the second terminal. In response to receiving a hold-call-back activation command from the first terminal via the packet-based network, the call server splits the first connection from the second connection, terminates the first connection and parks the second connection. The call server may then repeatedly prompt the second terminal for a call reestablishment command.
