Automatic Call Routing Device Abstract A call routing device connects a telephone set and a modem to a common line so that incoming calls from a modem are routed to the modem and incoming cells from a telephone set are routed to the telephone set. The call routing device selectively places a ringing signal on an extension line to the telephone set and places a lingback signal on the telephone line for the calling party. The call routing device is responsive to a code from the calling party for placing a ringing signal on an extension line to the modem enabling a ring detector to answer, connecting the modem to the line. The call routing device grants access to the first of the telephone set and modem to seize the telephone line and blocks access to the second one to seize the trunk line. 0405-1-0380
