Abstract:
1. A system for packet network telecommunication having a server unit, which has a control unit, and a client unit, which has a computer program product, embodied on a computer readable medium having computer program code stored thereon, for telecommunication, said system comprising at least in the computer program product, computer program code for receiving and transmitting, over a packet telecommunication network to a communication device that is different than the server unit, a data stream using a certain protocol supporting voice data transmission, in the computer program product, computer program code for transmitting, over a communication channel to the control unit, first call control commands that are in a first format, the communication channel being different than the packet telecommunication network, in the control unit, computer program code for receiving, over the communication channel from the client unit, the first call control commands that are in the first format, in the control unit, computer program code for modifying the first call control commands received from the client unit in the first format to a second format used by a network element in the packet telecommunication network, the network element being different than the communication device, in the control unit, computer program code for directing the network element to perform a call control action that enables establishment of a connection, over the packet telecommunication network, between the client unit and the communication device by transmitting, over the packet telecommunication network to the network element, the modified first call control commands, in the control unit, computer program code for receiving, over the packet telecommunication network from the network element, second call control commands that are in the second format, in the control unit, computer program code for modifying the second call control commands received from the network element in the second format to the first format, in the control unit, computer program code for transmitting, over the communication channel to the client unit, the modified second call control commands, in the computer program product, computer program code for receiving, over the communication channel from the control unit, the modified second call control commands, and in the computer program product, computer program code for, based on the modified second call control commands, transmitting, directly to the packet telecommunication network, the data stream for delivery to the communication device.
