allowing a central business communication system to handle all aspects of call setup on a remote switch. Call control for a telecommunication call set up on a remote switch continues to be handled by the central business communication system; however, the switching of the bearer channels is performed automatically on the remote switch if the telecommunication call is between telecommunication terminals on the remote switch. In addition, if the telecommunication call is between two remote switches, the remote switches will automatically communicate the bearer channels through an interconnecting media without going through the central business communication system. In addition, when an Internet protocol (IP) such as IETF RFC 791 is utilized to communicate the bearer channels between the central business communication system and the remote switch, multi-frequency dialing tones received from analog telephones connected to the remote switching network are converted to digital information before transmission via the IP communication channels to the central business telecommunication system.
