A method and apparatus for processing incoming telephone calls to a telephone control system. The apparatus includes a memory for storing electronic signals including signals representative of telephone network addresses and a processing unit for processing an incoming telephone call from a caller. Information is communicated by the processing unit to said caller indicating that the incoming call can be routed (e.g. branched) to any one of at least two telephone network destinations. The processing unit responds to the transmission by the caller of a command corresponding to the desired telephone network address by routing the incoming call to the telephone network address corresponding to the command transmitted by said caller.
