Fill in the table after the detection is completed as below, where the values are the frequency and
On-and-Off ratio detected. Please click the “Accept” button. If connecting Gateway to a PBX extension line,
please do not set the detected busy tone of the PBX and the PSTN in the same set, otherwise the value
detected the first time will be overwritten.
