Global Sip Settings - Zycoo CooVox-U80 User Manual

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.
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.
