Epygi Technologies Hidden Pages for Quadro Advanced Configuration
If the Quadro detects signals with above-specified settings, it will close the call.
2. Disconnect notification by power interruption. The CO interrupts the power on the
line to notify that the call party has hung up. To configure the Quadro to detect power
interruption, enable the Disconnect Detection checkbox. Specify the Disconnect
Duration setting, which is the minimum duration (ms) of power interruption to be
identified as disconnect notification. If the Quadro does not detect the power for the time
specified by the Disconnect Duration setting, it will close the call.
3. Disconnect notification by putting silence on the line. The CO puts silence on the line
to notify that the call party has hung up. To configure the Quadro to close the call upon
detecting silence, enable the Silence Detection checkbox and specify the following
settings:
o Min Duration: Minimum duration of silence the system should identify as a disconnect
notification.
o Threshold: Highest audio level that the system should identify as silence.
If the system detects audio lower than the specified threshold for more than the specified
duration, it will close the call.
•
Custom Fxo Data. Enables the manual configuration of different FXO related settings.
•
Voice Activity Level: Lowest audio level (dial tone) the system should detect on an FXO line
to know that the line is working. The activity detection takes place each time the system takes
the FXO line off hook to make an outgoing call.
•
Voice Activity Timeout: Maximum length of time that the system will wait for the voice
activity on an FXO line. If the system does not detect the required voice activity level for the
specified length of time, it assumes that that the PSTN line is not working (or no PSTN line is
attached to the FXO port) and plays the notification message, “Check your external phone
line.”
Please Note: The Voice Activity Level and Voice Activity Timeout settings take effect
only if the Wait for dialtone checkbox in the fxoconfig.cgi is enabled for the corresponding
FXO line (see section 3.6
).
