Automatic redialing arrangement for multi-line telephone station sets

Abstract From the Canadian patent

Abstract, The subject arrangement provides a last number dialed automatic redialing capability for each line of a multi-line telephone station set or attendant console. This is accomplished by maintaining a centralized last number dialed table on a per-line basis in the telephone switching system processor. When a subscriber subsequently accesses a line and operates the REDIAL key on the station set, the system processor retrieves the stored last number dialed for that line and completes a call connection to the identified destination.
