Abstract: PURPOSE: A method for forwarding calls in networking by an analog trunk in a private exchange, is provided to occupy one E and M line in call forwarding without occupying two E and M lines, thereby enhancing the efficiency of an E and M trunk and reducing a call loss. CONSTITUTION: In a state that an A-party(original caller) of the first exchange and a C-party of the second exchange mutually perform speech, the second exchange releases the occupation of an analog E and M trunk by trunk flashing of the C-party. When exceeding a trunk flashing time, the second exchange re-occupies the analog E and M trunk. The first exchange detects an occupation release state of the analog E and M trunk. If re-occupation of the analog E and M trunk is detected within a setup time, the A-party is made to be a holding state to prepare for receiving a dial number. If the second exchange re-occupies the analog E and M trunk, the C-party performs dialing to a D-party number of the first exchange. If the dialing number is received to the first exchange, the D-party of the first exchange is called. After the second exchange performs dialing, the C-party performs hang-up and call forwarding function, to release the occupation of the analog E and M trunk. If the release of the analog E and M trunk occupation is detected in the first exchange, a speech path between the A-party and the D-party of the first exchange is connected.
