As shown in the figure, the remote diagnostic method of the present invention receives a diagnostic application date, a diagnostic target trunk gateway 130 and a connection duration time from the operator through the operating terminal (110) (S401). The IP-IVR server 123 generates a diagnostic rule and stores the diagnostic rule in the DB 125 (S403).

When the IP-IVR server 123 periodically checks the diagnosis time according to the diagnosis rule (S405), and confirms that the diagnosis time is the diagnosis time of the trunk gateway 130, the IP-IVR server 123 determines the trunk gateway. Attempt to connect the call to the unique call number per trunk of 130 (S403).

Then, check whether the response of the voice providing unit 140 is received (S409), if not received in order to determine whether there is an abnormality of the trunk call record and error, that is, the diagnosis result is stored in the DB (125) (S415).

When receiving a response from the voice providing unit 140, the voice received from the voice providing unit 140 is stored in a file format (S411). At this time, the received response voice may be stored in a wave (.wav) file format.

After performing these steps (S407, S409 and S409) for the duration of the connection (S413), if the connection duration is exceeded, the call record and the result, that is, the diagnostic result is stored in the DB 125 (S415).

If a plurality of trunk gateways 130 are to be diagnosed (S417), the diagnostic rules are set as described above, and the steps S405 to S415 are multiplied according to the broadcasting function of the IP-IVR server 123. Can be done as

When the diagnosis of the trunk gateway 130 is completed according to the present invention, an operator can easily determine the state of the trunk even by comparing only the size of the trunk-specific voice (eg, wave file) stored in the DB 125. .

This is based on the assumption that the size of voice files stored at the same connection duration is almost the same.

For trunks with significantly smaller sizes of voice files (e.g., wave files) stored in the DB 125, the voices transmitted by the voice providing unit 140 are not IP-IVR due to poor connection status of trunks. Considering that the transfer to the server 123 is not easy, it is possible to diagnose the state of the trunk by listening to the voice provided by the voice provider 140 through an immediate diagnosis rather than a scheduled diagnosis.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.

As described above, the present invention has an effect of allowing the trunk gateway to be remotely diagnosed through a network according to a preset diagnostic rule, so that the trunk gateway can be easily checked for failure.

In addition, the present invention has the effect of increasing the call completion rate and call quality by remotely diagnosing the trunk gateway through the network according to a preset diagnostic rule to determine whether the trunk gateway is broken early.
