The utility model relates to an electric power department voice channel-testing system capable of realizing automatic answering function, and belongs to the technical field of communication equipment. A technical solution lies in that a work station (1), a front-end processor (2) with multi-channel analogue voice cards and a Wed server (3) are connected with a stored program control exchange (4) respectively; automatic voice channel-testing terminals (6) are connected with the stored program control exchange (4) through a transmission device (5); the automatic voice channel-testing terminals (6) are provided with one or more and comprise a power unit, an intelligent control unit, a ringing testing unit and a DTMF transceiving unit. The electric power department voice channel-testing system can realize tests for communication quality of dispatching telephones and administrative telephones automatically, and relieves workers at a communication dispatching center from onerous voice channel tests. The electric power department voice channel-testing system has the functions of timing, automatically/manually testing all/partial of telephones, testing the dispatching telephones and the administrative telephones, saving test results automatically and being compactable with DTMF systems. The electric power department voice channel-testing system has high security, strong compatibility and accurate measurement.
