1. A method, comprising:
- establishing, via a server device, a circuit-switched connection between a first device associated with a first party and a second device associated with a second party;
based on establishing the circuit-switched connection, retrieving, via the server device and from a memory, a first network address and a second network address for a packet switched network, the first address being associated with a third device associated with the first party, and the second network address being associated with a fourth device associated with the second party;
establishing, via the server device and on the packet-switched network, a packet-switched connection between the third device and the second device, the packet-switched connection being based on the first network address and the second network address;
terminating the circuit-switched connection based on establishing the packet-switched connection; and
transmitting video, for a video conference between the third device and the fourth device, via the packet-switched connection.

Abstract
A video conferencing system (100) includes a switch (125), a server (140), a telephony device (152), and a node (102) in a packet-switched network (135). The switch (125) establishes a circuit-switched connection between a calling party number and a called party number. The server (140) associates first and second network addresses in a packet-switched network (135) with each of the called party and calling party numbers. The telephony device (152) transmits audio data via the circuit-switched connection. The node (102) in the packet-switched network (135) transmits packetized video between the first and second network addresses responsive to establishment of the circuit-switched connection.

11. A non-transitory computer-readable storage medium to store instructions, the instructions comprising:
-
one or more instructions that, when executed by a processor in a computer device, cause the processor to; establish a circuit-switched connection between a first device associated with a first party and a second device associated with a second party; based on establishing the circuit-switched connection, retrieve, from a memory, a first network address and a second network address on a packet switched network, the first network address being associated with a third device associated with the first party, and the second network address being associated with a fourth device associated with the second party; establish, on a packet-switched network and based on the first network address and the second network address, a packet-switched connection between the third device and the fourth device; terminate the circuit-switched connection based on establishing the packet switched connection; and transmit video and audio for a video conference via the packet-switched connection. - View Dependent Claims (12, 13, 14, 15)

16. A device, comprising:
-
a memory; and a processor to; receive a called party identifier of a called party from a calling party having a calling party identifier, establish a circuit-switched connection based on the called party identifier and the calling party identifier, based on establishing the circuit-switched connection, determine, through access to the memory, a called party Internet protocol (IP) address based on the called party identifier and a calling party IP address based on the calling party identifier, establish a packet-switched connection based on the called party IP address and the calling party IP address, terminate the circuit-switched connection based on establishing the packet-switched connection, forward, via the packet-switched connection, first video and audio data from the calling party IP address to the called party IP address, and forward, via the packet-switched connection, second video and audio data from the called party IP address to calling party IP address. - View Dependent Claims (17, 18, 19, 20, 21)
