User's Manual
Note: If the functionality is configured for a specific Tel Profile,
the settings of the global parameter is ignored for calls
associated with the Tel Profile.
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 the parameter are enabled, the
device dials the phone number (to the PSTN/PBX line) only
after it detects a dial tone.
If the parameter is disabled, the device immediately dials the
phone number after seizing the PSTN/PBX line without
'listening' for a dial tone.
Note:

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 device initiates 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.
The parameter is typically set to between 5 and 8. The default
