  • multi-destination call delivery services such as extension phone, hunt group or call forwarding
  • a business assigns a single directory number (often referred to in the art as a "pilot" number) as the primary number to be used by callers in making voice telecommunications contact with that business.
  • a number of agents or operators are then used to field incoming telephone calls made to the pilot number. Transfer of incoming calls to individual ones of the agents is effectuated through the use of a multi-destination call delivery service (such as extension phone, hunt group or call forwarding) implemented by either the telephone service provider or the business itself (often through the use of a private branch exchange ⁇ PBX).
  • a multi-destination call delivery service such as extension phone, hunt group or call forwarding
  • Such services in general respond to an incoming call by potentially alerting one or more telecommunications agent terminals, and then through connecting the call to the agent terminal which answers.
  • an incoming call results in the simultaneous alerting of plural agent terminals. Any of the alerted agent terminals may then answer the call.
  • an "automatic privacy" feature is activated following an agent answering of the call to lock out all of the non-answering agent terminals from further participating in the call.
  • an incoming call prompts the scanning of an agent terminal identification list followed by the alerting of an identified idle one of the agent terminals found on that list. The call is then through connected when the agent with the idle terminal answers. If no agent terminals are idle, a voice mail message may be left or the incoming call is placed on hold in a queue for subsequent answering, and the caller is provided with an appropriate recorded announcement.
  • Telephone calls dialed to a pilot number associated with a plurality of agent terminals are received and directed to an available agent terminal for answering by means of an appropriate multi-destination call delivery service.
  • the calling party identification of the caller is automatically saved (or manually saved at the agent's instruction) and associated with a terminal identification for the agent who answers the call.
  • the calling party identification of the caller is compared to the saved calling party identifications. If there is a match, indicating that a prior incoming call from that caller has been received, the multi-destination call delivery service is by-passed.
  • the stored associated terminal identification for the agent who previously handled that prior incoming call is then retrieved and used to specify a call delivery destination for the current incoming call back to that agent terminal.

Furthermore, the present invention may be implemented in a number of telephone environments, including wireline, wireless, and private branch exchange.

The calling party may then indicate with a service code a desire for the conventional multi- destination call delivery service to be implemented without use of the return to prior agent feature. Furthermore, in instances where the automatic registration of the calling party identification to the party-agent list is deactivated, an agent may still register a calling party to the list by entering a service code through the terminal during or after the call.

Abstract

L'invention concerne un service de remise d'appels multi-destinataire (tel qu'un poste de standard privé, un groupe de recherche ou un transfert d'appel), ce service approprié étant exploité (110) dans un environnement de central téléphonique filaire, radio ou privé. Dans le cas de ce service appliqué aux appels entrants, l'identification d'un appelant est sauvegardée (112) dans une liste et associée à un numéro d'identification de terminal à l'intention d'un agent qui répond ultérieurement à l'appel entrant. En plus, lorsque l'appel entrant est d'abord reçu (100), l'identification (102) de l'appelant est comparée (104) à la liste mémorisée contenant les identifications des appelants. En cas de concordance (106), c'est-à-dire qu'un appel de cet appelant a déjà été reçu antérieurement, le service de remise (110) d'appels multi-destinataire est court-circuité. Le numéro d'identification terminal associé et mémorisé à l'intention de l'agent ayant traité précédemment le l'appel entrant antérieur est alors récupéré (116) et utilisé pour spécifier à ce terminal d'agent (118) un destinataire de remise d'appel pour l'appel entrant courant.
