Line Settings

   

 

 

Listening Volume: Adjusts the hearing volume. 

 

 

Speaking Volume: Adjusts the speaking volume.   

 

 

Tone Volume: Adds a new option to make tone volume adjustable. This setting will be 
applied to all tones generated by the gateway including Dial Tone, Busy Tone, and so 
on. 

 

 

Flash Time:

 

FXS: Used to adjust the detecting period of flash signal from the phone set connected to 

the FXS port. For example, if pressing the HOLD key will disconnect a call, increase 
the “Flash Detect Time” should fix this issue. 

FXO: Used to set the time frame that FXO generates a FLASH signal.

 

 

Enable Polarity Reversal: 

FXS: As the remote site answer this call or hook on 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 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 ITSP. 

 

PSTN Ring OFF Length: FXO/PSTN make out if the call from PSTN hangs up before 
FXS answer the call. 

※

 

Voice 

 

 

Preferred Codec Type: Since different voice codec have different compression ratios, so 
the sound quality and occupied bandwidths are also different. It is recommended to use 
the default provided (G.723.1) because it occupies less bandwidth and will provide 
better sound quality.
