Parameter Description
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 = (Default) Two-stage dialing. 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.
Note: This parameter can also be configured in a Tel Profile.
Web/EMS: Waiting For Dial Tone
[IsWaitForDialTone]
Determines whether or not the device waits for a dial tone
before dialing the phone number for IP-to-Tel (FXO) calls.

[0] No

[1] Yes (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.
Web: Time to Wait before Dialing
[msec]
EMS: Time Before Dial
[WaitForDialTime]
Defines the delay before the device starts dialing on the FXO
line in the following scenarios:

The delay between the time the line is seized and dialing
begins during the establishment of an IP-to-Tel call.
Note: Applicable only for one-stage dialing when the
parameter IsWaitForDialTone is disabled.

The delay between detection of a Wink and the start of
dialing during the establishment of an IP-to-Tel call (for DID
lines, EnableDIDWink is set to 1).

For call transfer - the delay after hook-flash is generated
and dialing begins.
The valid range (in milliseconds) is 0 to 20,000 (i.e., 20
seconds). The default is 1,000 (i.e., 1 second).
Web: Ring Detection Timeout [sec]
EMS: Timeout Between Rings
[FXOBetweenRingTime]
Defines the timeout (in seconds) for detecting the second ring
after the first detected ring.
If automatic dialing is not used and Caller ID is enabled, the
device seizes the line after detection of the second ring signal
