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 DVG-3016S including Dial Tone, Busy Tone, and

so on.

 Flash Time: 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.

 Enable Polarity Reversal: As the remote site answer this call or hook on the FXS port will

reverse the polarity.

 PSTN Answer Detection: This is used only by ITSP.

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

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.

 Jitter Buffer: Adjusts the jitter to receive a packet. If the jitter range is too wide, it will

delay voice transmission.

 Silence Suppression: If one side of a connection is not speaking, the system will stop

sending voice data (package) to decrease bandwidth usage.

 Echo Canceling: Prevents poor telecommunication quality caused by echo interference.

 Packet Time: Defines how long the DVG-3016S send a RTP packet-voice packet- to the

other side. The smaller the value, the more bandwidth usage. The larger the value, the

more voice delay.

 Approximate Bandwidth Require: The bandwidth required varies with Codec format and

packet time.
