UDT Detection
If the CPT auto detect function is not able to determine whether or not a PSTN-call receiving party has hung
up the phone, then the UDT detection function can serve as a back up. To do this, enter the high/low
frequency parameters from the CPT table into the UDP table.
NOTE: If FXO cut off calls un-normally, please disable this function.
