Epygi QX series User Manual

Hidden Pages for QX Advanced Configuration
o 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 QX 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.
o If the system detects audio lower than the specified threshold for more than the specified
duration, it will close the call.
The Custom Fxo Data checkbox 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
).
• Caller ID: Different standards of Caller ID transmissions. The standard appropriate to the local
telephony company should be chosen from this list.
Please Note: The selected standard takes effect only if the Caller ID setting for the
corresponding FXO line is set to Default in the fxoconfig.cgi. Otherwise, the standard selected
in fxoconfig.cgi will be used.
• Current Detection Timeout: Maximum length of time that the system will wait for the current
on an FXO line to know that the line is working. On call origination, if the system does not
detect the current within this timeout, it assumes 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 Current Detection Timeout setting takes effect only if the Current
Detection checkbox in the fxoconfig.cgi is enabled for the FXO line (see section 3.6
).
• Fxo Csrs: Country-specific regional setting that should correspond to the line settings of the
local telephony company. The value for this setting is set according to the regional settings
selected in the System Configuration wizard. Please do not modify this setting unless
instructed to do so by Epygi’s technical support engineers.
• Fxo Ring Stop Timeout: Period of time after which the system will validate ringing termination
if no new ring pulse is received from CO. The value for this setting should be slightly greater
than the time between two successive ringing signals sent by CO. Note that too small value for
this setting will cause the system to drop the call before the next ringing signal arrives. Too
large of a value will cause the system to ring the phone long after the remote party has hung
up, i.e. if the remote party hangs up before this timeout expires, the local user will hear busy
tones when answering the ringing phone.
• Off-hook Delay: Delay time (in milliseconds) for incoming calls on FXO line to avoid the ring
tone playing with some providers.
• Enable On Hook Monitoring: Enables on-hook monitoring of Caller ID signals. If selected, the
system will continuously monitor FXO lines to detect Caller ID signals that are not preceded by
