Dialing:
–
Provisional dialing method – dialling type for the line (before loop short):

DTMF – tone;

pulse – pulse.
–
Dialing method – dialling type for the line (after loop short):

DTMF – tone;

pulse – pulse.
For DTMF method:

Pause duration (ms) – pause duration, in milliseconds;

Tone duration (ms) – tone duration, in milliseconds.
For pulse method:

Interdigit delay – time interval between digits when dialling for the analogue phone line. Default
value is 200ms;

Pulse time (ms) – pulse duration, in milliseconds;

Pause time (ms) – pause duration, in milliseconds.
Incoming direction parameters :
–
Ring detection – quantity of rings, that will be used by FXO for loop closure ('offhook') and transmitting the
'PBX response' tone into the line. Default value is 2. If there is a continuous inductor on the line, this
parameter must be set to 1;
–
PSTN number prefix – prefix added to the number in CallerID sent to VoIP;
–
PSTN number prefix – prefix added to the name in CallerID sent to VoIP;
–
Use PSTN CallerID – when checked, use CallerID received from the phone line for VoIP direction call,
otherwise it will not be used;
–
Detect FXO line presence – detection of subscriber's line connection to FXO for the line status view in
monitoring.
–
Block FXO line in outgoing direction – block FXO set, if the subscriber's line is not connected to it.
Tone detect parameters :
–
Minimum level of detectable signal, dBm – minimum level of detectable 'PBX response' and 'busy' tones,
permitted values – from -20 to -40dBm;
–
Dialtone detection parameters – 'PBX response' tone detection parameters;
–
Busytone detection parameters – 'busy' tone detection parameters.
–
Ringback tone detection parameters – ringback tone detection parameters.
When the ringing arrives to FXO set, this setting may result in transmission of false data into
monitoring on loss of subscriber's line connection.
