Definitions

  • the present invention relates to a method, according to the preamble of Claim 1, and a system, according to the preamble of Claim 11, for facilitating the work of a switchboard operator.
  • switchboard operator refers, for example, to a person who routes calls in a virtual telephone switchboard, in which distributed response series are used.
  • the term distributed response series refers to a response series, the telephone subscribers of which can be located under several different telephone exchanges, for example, in different parts of the country.
  • a call made to a telephone number of a distributed response series is routed to one of the subscriptions belonging to the response series.
  • a distributed response series is highly suitable, for example, for implementing advice services, as the people who can be contacted from the telephone number of the response series can work at home and experts in several locations can be gathered into the response series.
  • virtual telephone switchboard refers to an arrangement, in which telephone mainlines connected under a virtual switchboard, and which are located under the control of at least two branch exchanges, are intended to be controlled in the same way as a conventional telephone switchboard controls extensions.
  • a functioning virtual telephone switchboard permits, for example, the telephone lines and mobile connections of the various units of a large company to be controlled from a single service point, thus improving the employees' contactability. In such a case, a customer calling the company's number will be more likely to contact the person they wish, or that person's deputy, irrespective of the specific unit in which the desired person is working at that precise moment. The caller can also be informed immediately, if the person they are seeking cannot be contacted.
  • a contactability chain for instance, can be created for a specific telephone number, the chain comprising several other telephone numbers and/or other telecommunications network addresses.
  • a call is made to the telephone number, it is connected according to the contactability chain, for example, in the manner described in the following.
  • the call is connected to the first number of the contactability chain. If there is no response from this first number, or if a connection cannot be made to it, the call is connected to the second number in the contactability chain. The call goes on being connected until either the call is answered, or until the alternatives in the contactability chain have been all gone through.
  • the call is connected to the telephone switchboard operator, who tries to serve the caller to the best of their ability and connect the call to a suitable extension.
  • the switchboard operators may be informed of the number called by the caller. In that case, the switchboard operator can tell the caller, for example, that the person desired is in a meeting, or that the service is temporarily congested. It is also usual that the switchboard operator does not even know who the caller has tried to contact, or in which service they are interested.
  • the contactability chain there may also be other telecommunications network targets, such as a voice mailbox.
  • the call may also be routed, with the aid of a VoIP connection (voice over internet protocol), for example, to the remote work PC of the person desired.
  • VoIP connection voice over internet protocol
  • the switchboard operator is notified of the number to which the caller in question has originally called, and possibly also of a reason code or similar, which states why the call has been routed to the switchboard.
  • the reason code may, for example, state that the last extension, to which the call was attempted to be connected, was busy.
  • a basic drawback in the solutions referred to above is that, when the call finally reaches the switchboard operator, often after a long search chain, the switchboard operator may not necessarily know at which numbers or at which destinations an attempt has been made to contact the desired person, prior to the call being connected to the switchboard. The caller is then often quite exasperated at not being able to contact the person desired, or at the desired service not being available at that moment. In such a situation, the caller hopes that the switchboard operator could expertly guide them to a suitable number. The switchboard operator, however, does not know how the call has been routed in the network and to which extension numbers or addresses an attempt has already been made to connect the call.
  • the switchboard operator may once again route the call to the contactability chain, in which yet another attempt is made to contact the person at the same telephone extensions as previously.
  • the customer cannot tell the switchboard operator at which extensions an attempt has been made to contact the person to be contacted, as this information has not been given to the customer.
  • the switchboard operator may also try to connect the call to a mobile phone that is outside the coverage area, to voice mail that is full, or as a NoIP connection to the person's remote work PC, even though a NoIP connection is not available.
  • the invention is intended to create a method, by means of which a switchboard operator can give callers better service.
  • connection history refers to information on the extensions to which an attempt has already been made to connect the call in question, without result.
  • information on the state of the extensions refers to information, for example, as to whether a telephone extension is free, busy, or cannot be contacted. If a call transfer has been used to route calls coming to the extension to some other extension, information on this can also be included in the state information.
  • the state information can also include information on the possessor of the extension, such as their holidays or work trips.
  • the state information can also include information on the contactability of the possessor of the extension in question, for example, as to whether the possessor of the extension is on holiday or on a trip, and possibly also information on how or where the person in question can be contacted.

  • the switchboard operator can decide how the caller should be served in the situation in question.
  • the switchboard operator has more extensive information than previously on which to base a decision on the further processing of the call.

Abstract

L'invention concerne un procédé et un système au moyen desquels on peut faciliter le travail d'un opérateur de central et améliorer la possibilité de service au client de l'opérateur. Si un appel entrant est connecté automatiquement à différentes extensions (G, J, N, L) sur la base d'une chaîne de possibilités de contacts, sans cependant qu'une connexion soit établie, l'appel est acheminé vers l'opérateur de central. L'inconvénient tient à ce que l'opérateur du central ne connaît pas nécessairement à quels numéros une tentative a été faite afin de contacter la personne à contacter. Selon l'invention, l'information sur l'appel acheminé vers l'opérateur de central, par exemple, l'information portant sur quelles extensions (G, J, N, L) les tentatives d'appel ont eu lieu, est mise à disposition de l'opérateur au moyen d'une interface utilisateur graphique (Q). Sur la base de l'information présentée par cette interface (Q), l'opérateur de central peut connecter l'appel sur un numéro adéquat, ou décider de répondre à l'appelant d'une autre manière, par exemple, en prenant une demande de rappel. L'interface graphique utilisateur (Q) permet aussi de montrer l'état des extensions (G, J, N, L).
