NOTE: To cope with different local PSTN and different PBX models, the system
provides auto busy tone cadence learning to prevent the FXO from engaging a
line. However, if the line of the receiving party is engaged and his/her PSTN uses
a voice prompt to replace the traditional beep sound, then the system would not
be able to detect a busy tone. Silence detection should then be used to determine
whether or not to end the call.
CPT Auto Detect
• 2 PSTN phone numbers or 2 PBX extension lines are needed.
• Connect one of the phone sets to a FXO port.
• The line of “Dial Number” must be on-hook. Set the outgoing phone number the same as the phone
line that is in use as above, and click the “Accept” button to start detection.
• If detection is successful, the parameters obtained will automatically be inserted into the CPT
parameter.
• Save settings and restart the system.
Detailed description is given below:
Click “CPT auto detect” at the bottom of Trunk CPT Settings.
If CPT auto detect is used, the function would halt every operation of the Gateway. Select “I am sure of it”,
and then click the “Accept” button. Wait for 15 seconds, and then you will enter CPT auto detect window.
