Global Sip Settings - D-Link DVX-2002F User Manual

General
Opermode: Set the Opermode for FXO Ports.

ToneZone: Select the tone zone of your country.

Ring Timeout(s): FXO (FXS signaled) devices must have a timeout to determine if it should

hang up before the line is answered. This value can be tweaked to shortenhow long it takes
before DAHDI considers a non-ringing line to have hung-up.
Relax DTMF: Helps DTMF signal detection.

Send Caller ID After: Certain countries (UK) have ring tones with different ring tones

(ring-ring),which means the caller ID needs to be set later on, and not just afterthe first ring,
as per the default (1).
Echo Cancel: Enable/Disable software Echo Cancel algorithm.

Denoice:The denoise parameter will help on noise reduction of the noisy analog lines,

especially when gains have been increased on the lines.
Echo Training: Enabling echo training will cause the PBX system to mute the channel, send

an impulse, and use the impulse response to pre-train the echo canceller so it can start out
with a much closer idea of the actual echo. Value may be "yes", "no", or a number of
milliseconds to delay before training (default = 400). This option does not apply to hardware
echo cancellers.
