Fax Settings
NOTE:
When a fax tone is detected in a call, the gateway will automatically switch from voice mode to fax
mode. So fax settings will be temporarily applied to a specific port which detects fax tones, instead of
its default voice settings.
y
Enable High Quality:
The system sends the same fax frame twice to get a high quality fax transmission.
Enabling this variable increases bandwidth requirements.
y
T.30:
The system uses T.30 as the protocol for fax transmission. The parameter settings are the same as
for voice transmission. However, enabling the T.30 protocol will consume more network resources and will
affect transmission quality.
y
NOTE:
When you send fax over an IP network it needs your network to support fax over IP
functionality (either T.38 or T.30). Please consult your VoIP service provider for this setting.
Drop Inactive Call
This is used as a standard to determine whether or not to hang up the phone. The system will hang up the
phone automatically to avoid keeping the line engaged if the detected volume is below the Silence Detection
Threshold and the time exceeds the Drop Silent Call Timeout.
y
Silence Detection Threshold
: The volume below the threshold is used as a standard to determine
whether or not to hang up the phone.
y
Drop Silent Call Timeout:
If the detected volume is below the threshold and the time exceeds the silence
detection interval, the system will hang up the phone automatically to avoid keeping the line engaged.
NOTE:
Please be careful with these settings. Improper values might cause unexpected automatic
disconnection of a call. Default values are recommended.
