A method for recording a call

The present invention relates to a method for recording a call in the control of a calling subscriber according to the preamble of claim 1, wherein the method comprises controlling the first 5 storage in the operator rigidity storing information transmitted over the telephone connection based on the audio frequency signals received from the calling subscriber.

The invention also relates to a method for recording a call in the control of a receiving interface according to the preamble of claim 6, wherein the method comprises controlling the first recording stream or the second recording stream system for storing information transmitted over the telephone connection from the receiving subscriber signal.

According to the prior art, in the situation where the receiving subscriber wishes to record a call in the operator's infrared system, the receiving subscriber must provide the calling subscriber with the telephone number of the 15 service centers responsible for recording the calls as his own telephone number information. The service center records the call passing through it and directs the call to the subscriber receiving the call. In the situation where the calling subscriber wants to record a call in the operator's ice-cream system, he / she calls the service center / server and informs him / her of the desired subscriber number. The service center then connects the call to the number of the desired receiving subscriber. This kind of waste ...: 20 has been implemented in Merling Systems' MCC "Call Recording" system.

: Telephone subscribers also have the ability to record calls or parts of calls to their own subscriber: *** subscriber devices.

• ·

A disadvantage of the prior art in the storage service implemented in an operator's rigid system is that the telephone subscriber must know beforehand whether he wants to record a call he has received or made. To record a call or part of a call, ·: · *: the calling subscriber must first call the customer-specific storage system telephone number: and enter the required password using the tone signals, followed by the number of the receiving subscriber. If, on the other hand, the subscriber receiving the call ·: ·· j wants to record the call or part of it, the calling subscriber must call the recording queue; 30 to direct the telephone connection through the storage system .... to the receiving subscriber. Particularly problematic here is the fact that the calling subscriber has to perform additional actions on the receiving subscriber to constrain the service to be provided. The receiving subscriber can divide the storage number into his own telephone number, so that after a service has been set up, the calling subscriber who starts communicating with the receiving subscriber does not have to incur extra time. In practice, switching both phone numbers causes extra effort for all those who have called the receiving subscriber prior to the change of telephone number and with whom the receiving subscriber wishes to record. In addition, if the receiving subscriber wishes to discontinue using the storage service, it is unnecessary to allocate the used storage system number to a 10-tone normal number for the receiving subscription and to overload the telephone network with additional call forwarding or to cause the called subscriber to call again.

The problem with the devices to be connected to the PSTN subscriber line of the subscriber is that the storage devices have to be installed on each subscriber line separately, which entails costs and hassle. The subscriber is responsible for maintaining its storage device and tracking the space required by the storage device.

It is an object of the invention to provide a completely new method of recording a call, by which the prior art problems described above can be solved.

...: 20 In the case of incoming calls, the invention is based on directing all: incoming calls to the storage server and initiating the recording of calls ''. and controlling the recording of calls by means of tone signals. With respect to outgoing calls, the invention is based on establishing a telephone connection to the receiving interface and the storage server if an off-hook signal of a certain duration is received from the calling interface.

. More specifically, the method of recording a call according to the invention ... under the control of a calling interface is characterized by what is claimed; mus 1.

·: * ·. A method according to the invention for recording a call in a receiving interface. The control of: 30 is also characterized by what is stated in the character -...: character portion of claim 6.

The invention provides considerable advantages. The telephone subscriber may make call setups; in connection with or during a call, he or she decides whether or not to record all or part of a call he or she has received or made on the operator's system. Also, the calling subscriber does not need to use additional telephone numbers in addition to the nor-5 paint telephone number of the receiving subscriber in order for the calling subscriber and / or receiving subscriber to record the call or part thereof. The fact that the calling subscriber is offered the opportunity to record all or part of a call does not require any action other than the normal call subscriber from the calling subscriber.

The subscriber subscriber does not have to worry about maintaining the storage system and the space needed for its storage systems.
