Connection Method
FXO connection methods include:
Option Description
Static
Binding
Bind the number which corresponds to an FXS port to an FXO
port. The number will be listed in the Bound Number column. This
helps to achieve the corresponding binding between an FXO port
and an FXS port (two-way).
Two
Stages
Dialing
Mode
(default)
Under this mode, an incoming call from an FXO port will go into
the IVR system. Then IVR will play a speech prompt “Please dial
the extension number”. If you fail to input the correct target station
number before IVR finishes the third repeat of the prompt, the
FXO will hang up the call automatically; otherwise, the
corresponding station will ring.
Note:
Both items Connection Method and Bound Number will be hidden if the SIP
Station feature is enabled on the SIP Settings interface.
Input Gain, Output
Gain
Adjusts the gain of the voice input to/ output from the FXO port. Range of value:
-24~12, calculated by dB, with the default value of 0.
Echo Canceller
The echo cancellation feature for a call conversation over the FXO channel. By
default, this feature is enabled and the effect can reach 128ms.
Forbid Outgoing
Call
If this feature is enabled, the FXO port will be forbidden to call out. The default
setting is
disabled
.
Caller ID Detection
If this feature is enabled, the FXO port will detect the caller IDs from the incoming
calls. The default setting is
disabled
.
Polarity Reversal
Detection
Once this feature is enabled, only when the FXO port detects the polarity reversal
signal will the corresponding channel go into the talking state. The default setting is
disabled

at the same time.
