ABSTRACT:
The invention is directed to a method of and apparatus for initiating a duplex communication in response to a received simplex communication. In one embodiment of a method of converting a simplex communication to a duplex communication a simplex message is received; a duplex communication protocol is transmitted in response; and a duplex communication is initiated based on the response. In another embodiment of a method of converting a simplex communication to a duplex communication, a simplex message from a sender is received that includes the sender's simplex ID. A duplex communication protocol associated with the sender's simplex ID is sought, and a duplex communication based on the duplex communication protocol is initiated when the protocol is received.
