Abstract

The present invention provides a voice gateway apparatus for allowing an IP telephone service to be easily introduced in an environment using a private branch exchange. The communication system including the voice gateway apparatus 30 of the present invention is generally constituted by a telephone terminal 10, a private branch exchange 20, the voice gateway apparatus 30, a call agent 40, an IP network 7 and a public switched telephone network 8. The voice gateway apparatus 30 is connected with: trunk lines 9 coupled to the private branch exchange 20, subscriber lines 4, and an xDSL modem 1 that transmits/receives digital signals by use of the subscriber lines 4. In addition to performing the functions of transforming voice band signals into IP packets and vice versa, the functions of transmitting/receiving voice band signals and IP packets are also provided.
