Name Description
Hook flash time
max Used by gateway to detect hook flash, the default is 800 milliseconds.
The gateway will regard the flash duration between Hook flash time min and Hook flash time
max as effective flash. Any flash lasting over the longest time will be considered by gateway as
hang up. Generally, this value should not be less than 800 milliseconds.
Caller ID
transmission mode Select transmission mode of Caller ID signal from the FXS port to the phone.

FSK or DTMF

SDMF or MDMF

Sending Caller ID data before or after ringing

Sending Caller ID data with or without parity
Hook debouncing Used by gateway to avoid phone status errors, with default of 50 milliseconds.
When the duration from hang-up to off-hook falls short of this value, the gateway will ignore the
status variation, and consider that the phone remains in hang-up status. In opposite case, the
gateway will ignore the status variation, and consider the phone remains in off-hook status.
Effective range of setting is 10~1000 milliseconds.
Ring frequency Set the ringing frequency to be transmitted by gateway to the phone, ranging from 15 to 50 Hz,
with default of 20 Hz.
Play busy tone for
network fault Play a busy tone upon off-hook when a network fault occurs.

range of setting is 15~180 seconds.
This parameter is used in combination with the Release control by caller parameter in

Outpulsing delay Used when gateway’s FXS port is connected with the trunk interface of PBXs. For calls from
gateway to PBX, gateways will relay the extensions to PBX after the delay set here. Setting of 0
means no extension number relay. The default is
0 milliseconds.
Loop open interval This parameter is used with the loop open disconnection request. The range is from 100 ms to
6000 ms.
Polarity reversal Set the trigger for polarity reversal, the default is Outgoing.
