SIP User's Manual A. Configuration Parameters Reference
Parameter Description

[0] = FXO line current limit is disabled (default).
 [1] = FXO loop current is limited to a maximum of 60 mA.
Note: For this parameter to take effect, a device reset is required.
[FXONumberOfRings]
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.
Web/EMS: Dialing Mode
[IsTwoStageDial]
Determines the dialing mode for IP-to-Tel (FXO) calls.
 [0] One Stage = One-stage dialing. In this mode, the device
seizes one of the available lines (according to the
ChannelSelectMode parameter), and then dials the destination
phone number received in the INVITE message. To specify
whether the dialing must start after detection of the dial tone or
immediately after seizing the line, use the IsWaitForDialTone
parameter.
 [1] Two Stages = Two-stage dialing (default). In this mode, 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.
Notes:
 This parameter is applicable only to FXO interfaces.
 This parameter can also be configured per Tel Profile, using the
TelProfile parameter.
Web/EMS: Waiting For Dial
Tone
[IsWaitForDialTone]
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 must be configured in the CPT
file.
 The device may take 1 to 3 seconds to detect a dial tone
(according to the dial tone configuration in the CPT file). If the
dial tone is not detected within 6 seconds, the device releases
the call and sends a SIP 500 "Server Internal Error” response.
 This parameter is applicable only to FXO interfaces.
