Line Settings
• Listening Volume: Adjusts the hearing volume.
• Speaking Volume: Adjusts the speaking volume.
• Tone Volume: This setting will be applied to all tones generated by the VoIP gateway including Dial
Tone, Busy Tone, and so on.
• Flash Time:
FXS: Used to adjust the detection period of flash signal from the phone set connected to the FXS
port. For example, if pressing the FLASH key disconnects a call, increase the “Flash Detect
Time” to fix this issue.
FXO: Used to set the time frame that FXO generates a FLASH signal.
• Enable Polarity Reversal:
FXS: As the remote site answers this call or goes on hook the FXS port will reverse the polarity.
FXO: This option forces the gateway to detect the reversal of polarity on FXO port as the primary
signal to drop a call. Some telephone switches or PBX systems reverse the line polarity to inform
the remote end to drop an ongoing call. Please consult with the telephone service provider for
availability of this feature.
• PSTN Answer Detection: This is only used with specific VoIP providers.
• PSTN Ring Off Length: This is for PSTN making out if the call rings off before picking up.
