Abstract

PURPOSE:To transfer a call to an extension intended by a caller by restoring a callee extension while a callee party is called and calling an extension of a replaced extension number. CONSTITUTION:In case of the private branch of automatic exchange operated in the additional dial-in system by means of a PB signal to a call from a trunk line 4, if an extension 1a being a callee party of the trunk line 4 does not reply and a trunk line subscriber being a caller calls other extension 1b having a number different from the final end digit belonging to the same private branch of automatic exchange as to the extension 1a, the caller calls the other extension 1b by dialing the prescribed one digit number. Thus, the caller is connected to the intended extension by a simple operation that the caller gives additional dial while the callee party does not respond and the caller listens to a call tone in this way.
