Table 6-51: General FXO Parameters

Determines the FXO line characteristics (AC and DC) according to
USA or TBR21 standard.
[66] = TBR21
[70] = United States (default)
Note: For this parameter to take effect, a device reset is required.
Defines the number of rings before the device's FXO interface answers
a call by seizing the line.
The valid range is 0 to 10. The default is 0.
When set to 0, the FXO seizes the line after one ring. When set to 1,
the FXO seizes the line after two rings.
Notes:
This parameter is applicable only if automatic dialing is not used.
If caller ID is enabled and if the number of rings defined by the
parameter RingsBeforeCallerID is greater than the number of rings
defined by this parameter, the greater value is used.
Determines the dialing mode for IP-to-Tel (FXO) calls.
[0] One Stage = One-stage dialing.
[1] Two Stages = Two-stage dialing (default).
If two-stage dialing is enabled, the device seizes one of the PSTN/PBX
lines without performing any dialing, connects the remote IP user to
the PSTN/PBX, and all further signaling (dialing and Call Progress
Tones) is performed directly with the PBX without the device's
intervention.
If one-stage dialing is enabled, the device seizes one of the available
lines (according to the parameter ChannelSelectMode), and dials the
destination phone number received in the INVITE message. Use the
parameter IsWaitForDialTone to specify whether the dialing must start
after detection of the dial tone or immediately after seizing the line.
Note: This parameter is applicable only to FXO interfaces.
Determines whether the device waits for a dial tone before dialing the
phone number for IP-to-Tel (FXO) calls.
[0] No = Don't wait for dial tone.
[1] Yes = Wait for dial tone (default).
When one-stage dialing and this parameter are enabled, the device
dials the phone number (to the PSTN/PBX line) only after it detects a
dial tone.
If this parameter is disabled, the device immediately dials the phone
number after seizing the PSTN/PBX line without 'listening' for a dial
tone.
Notes:
The correct dial tone parameters should be configured in the Call
Progress Tones file.
