Patent ID: 8634531

Claim:
A call server in a hybrid telecommunications network comprising: a network interface for connecting the call server to a packet-based network comprising at least a segment of the hybrid telecommunications network wherein a non-packet based network comprises another segment of the hybrid telecommunications network; a memory for storing one or more program modules; and a processor for executing the one or more program modules, wherein the one or more program modules comprise computer-executable instructions for causing the call server to: receive a call start command and a call record identifier from an application programming interface (API) via the packet-based network; access a database record to retrieve a call record associated with the call record identifier, wherein the call record includes a phone number of a calling party terminal and a phone number of a called party terminal; establish a first connection with the calling party terminal via the packet-based network by sending a first connection request to the phone number of the calling party terminal, establish a second connection with the called party terminal via the packet-based network by sending a second connection request to the phone number of the called party terminal, join the first connection with the second connection to establish communication between the calling party terminal and the called party terminal, park the second connection when the first connection is terminated or park the first connection when the second connection is terminated, establish a new connection with the calling party terminal via the packet-based network if the first connection was terminated or establish a new connection with the called party terminal via the packet-based network if the second connection was terminated, and join the new connection with the first or second connection to reestablish communication between the calling party terminal and the called party terminal.
