
[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.
For digital interfaces: Defines the delay after hook-flash is
generated and until dialing begins. Applies to call transfer (i.e., the
parameter TrunkTransferMode is set to 3) on CAS protocols.
For analog interfaces: 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, see
the EnableDIDWink parameter).

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).
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 (allowing
detection of caller ID sent between the first and the second rings).
If the second ring signal is not received within this timeout, the
device doesn't initiate a call to IP.
If automatic dialing is used, the deviceinitiates a call to IP when the
ringing signal is detected. The FXO line is seized only if the remote
IP party answers the call. If the remote party doesn't answer the
call and the second ring signal is not received within this timeout,
the device releases the IP call.
This parameter is typically set to between 5 and 8. The default is 8.
Notes:

This parameter is applicable only for Tel-to-IP calls.

This timeout is calculated from the end of the ring until the start
of the next ring. For example, if the ring cycle is two seconds on
and four seconds off, the timeout value should be configured to
five seconds (i.e., greater than the off time, e.g., four).
