APPARATUS AND METHOD FOR MAKING CALLS VIA INTERNET

摘要

Method for providing a connection between a plurality of communication devices coupled to an internet protocol (IP) network. The method includes the steps of: receiving a signal from a first device, the signal including the e-Num of the first device; authenticating the e-num; receiving an e-Num of a second device from the first device; and establishing a connection between the first and second devices via the IP network thereby enabling users of the first and second devices to have an audio communication through the connection. The method enables an e-Num user to make four types of phone calls: e-Num to e-Num, e-Num to public switched telephone network (PSTN), PSTN to e-Num, and PSTN to PSTN.
