Appeal No. 2005-0508
Application No. 09/024,923
Network Telephony (IPNT) calls in order to permit live
conversation between a user on a COST telephone connected to the
COST network and a user on an IPNT terminal connected to the
Internet.
Representative claim 1 is reproduced as follows:
1. A computerized telephony bridge unit, comprising:
a trunk-line port and associated circuitry for
receiving and placing Connection Oriented/Switched
Telephony (COST) telephone calls on a COST network;
a data network port and associated circuitry for
receiving and placing Internet Protocol Telephony Network
(IPNT) calls on the Internet;
conversion circuitry for converting data
representing calls dynamically between IPNT and COST
telephone calls and
a digitally-stored look-up table relating COST
telephone numbers to IP addresses;
characterized in that control routines functioning
as part of the bridge unit receive a first incoming call
from one of the COST and Internet networks, extract
specific data encoded into the incoming call, either COST
or IPNT, and use the extracted data to access the look-up
table to determine an associated COST telephone number or
IP address, and use the associated COST telephone number
or IP address to place a call associated with the
received call on the network other than the network on
which the call is received, and dynamically convert data
between the associated calls, and the dynamic conversion
of data enables two people to engage in a live
conversation even though one person is on the Internet
and the other is on a COST network.
