Item Description
Max Interval for
Dialing the Next
Digit
Specify the maximum interval for the user to dial the next digit.
This timer will restart each time the user dials a digit and will work in this way until all
the digits of the number are dialed. If the timer expires before the dialing is completed,
the user will be prompted to hang up and the call is terminated.
Max Interval
between Off-hook
and Dialing the First
Digit
Specify the maximum interval in seconds between off-hook and dialing the first digit.
Upon the expiration of the timer, the user will be prompted to hang up and the call is
terminated.
Dial Delay Time
Configure dial delay time.
By default, the dial delay time is 1 second.
Input Gain on the
Voice Interface
When the voice signals on the line
attenuate to a relatively great extent,
increases the voice input gain value.
IMPORTANT:
Gain adjustment might lead to call failures.
You are not recommended to adjust the
gain. If necessary, do it with the guidance
of technical personnel. Output Gain on the
Voice Interface
When a relatively small voice signal
power is needed on the output line,
increases the voice output gain value.
DTMF Detection
Sensitivity Level
Set the DTMF detection sensitivity level.
• Low—In this mode, the reliability is high, but DTMF tones might fail to be detected.
• Medium—In this mode, the reliability is medium. If you select this option, you can
specify the Frequency Tolerance of Medium DTMF Detection Sensitivity Level. The
greater the value, the higher the probability of false detection. Support for this
option varies with installed cards.
• High—In this mode, the reliability is low and detection errors might occur.
