In one such connection, the user is afforded enhanced directory assistance upon a user command in the form of an out-of-band signaling message, e.g., SS7 signaling message. For example, the user may be afforded further operator assistance by pressing on the user telephone a predetermined key (e.g., �*� key), which is detectable by the directory assistance service provider as an SS7 signaling message.

BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1 a-b are block diagrams depicting a prior art SS7 network.
DETAILED DESCRIPTION The present invention contemplates a directory assistance center operating in conjunction with a SS7 network. Turning to FIG. 1 a, a SS7 network by functional component is shown. A SS7 network is composed of a plurality of service switch points (SSP), signal transfer points (STP) and signal control points (SCP). An SSP is generally a telecommunications switch, access tandem or end office which can interact with the SS7 network for data base services. For purposes of the present invention, the SS7 network node of the directory assistance center disclosed herein operates as an SSP.
If, after initiation of a transfer (whether or not it succeeds) and at any time before the caller hangs up, the caller requires further operator assistance, the caller can perform a return transfer back to an operator (hereafter referred to as �return transfer� or �transfer back�). This is done simply by pressing the �*� (star) key or another designated key on the caller's telephone once or twice (depending on the system, and as instructed by the operator in the signoff message). Generation and detection of the customer-issued return transfer command can occur through DTMF tones or through SS7 signaling messages. The underlying call transport system is a SS7 network.
Such a manual disabling of the return transfer SS7 message or DTMF tone detection can occur, for example, when a caller is inadvertently transferred back to the operator by using the key to access a service at the destination number. The caller can note the problem to the operator, who can disable the feature and reconnect the caller to the destination number. In other situations, the caller may know in advance that the destination number makes use of the �*� key (e.g. for electronic banking), and can request that the operator disable the return transfer SS7 message or DTMF tone detection before the connection is first made.
