Version 6.8
Determines whether the device adds the Blind Transfer code
(defined by the KeyBlindTransfer parameter) to the dialed
destination number.

[0] Disable (default)

[1] Enable
Note: This parameter is applicable only to FXO and FXS
interfaces.
Defines the duration (in milliseconds) for which the device
waits for a disconnection from the Tel side after the Blind
Transfer Code (KeyBlindTransfer) has been identified. When
this timer expires, a SIP REFER message is sent toward the
IP side. If this parameter is set to 0, the REFER message is
immediately sent.
The valid value range is 0 to 1,000,000. The default is 0.
Enables QSIG transfer for IP-to-Tel and Tel-to-IP calls.

[0] IP2QSIGTransfer = (Default) Enables IP-to-QSIG
transfer.

[1] QSIG2IPTransfer = Enables QSIG-to-IP transfer.
Defines the maximum duration (timeout) to wait between call
Setup and Facility with Redirecting Number for replacing the
calling number (for Tel-to-IP calls).
The valid value range is 0 to 10,000 msec. The default is 0.
The interworking of the received Setup message to a SIP
INVITE is suspended when this parameter is set to any value
greater than 0. This means that the redirecting number in the
Setup message is not checked. When a subsequent Facility
with Call Transfer Complete/Update is received with a non-
empty Redirection Number, the Calling Number is replaced
with the received redirect number in the sent INVITE
message.
If the timeout expires, the device sends the INVITE without
changing the calling number.
Notes:

The suspension of the INVITE message occurs for all calls.

This parameter is applicable to QSIG.
Enables call transfer using re-INVITEs.

[0] Disable = (Default) Call transfer is done using REFER
messages.

[1] Enable = Call transfer is done by sending re-INVITE
messages (instead of REFER).
Notes:

The device uses two DSP channels per transferred call.
Thus, to use this feature, you also need to configure the
maximum number of available DSP channels, using the
MediaChannels parameter.

This parameter is applicable only to FXS interfaces.
Determines the interworking of incoming mid-call SIP REFER
messages to outgoing REFER messages, for calls pertaining
to the IP-to-IP application.

[0] Disable = (Default) Upon receipt of a REFER message,
