User's Manual
Determines whether the device allows ISDN ECT, RLT or TBCT IP-to-
Tel call transfers between B-channels of different Trunk Groups.

[0] = (Default) Disable - ISDN call transfer is only between B-
channels of the same Trunk Group.

[1] = Enable - the device performs ISDN transfer between any two
PSTN calls (between any Trunk Group) handled by the device.
Note: The ISDN transfer also requires that you configure the parameter
TrunkTransferMode_x to 2.
Defines the IP-to-ISDN Transfer Capability of the Bearer Capability IE in
ISDN Setup messages, per trunk.

[-1] Not Configured

[0] Audio 3.1 (default)

[1] Speech

[2] Data
Notes:

If this parameter is not configured or is set to -1, Audio 3.1 capability
is used.

The Audio 7 option is currently not supported.

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.
Defines the ISDN Transfer Capability for data calls.

[0] = (Default) ISDN Transfer Capability for data calls is 64k
unrestricted (data).

[1] = ISDN Transfer Capability for data calls is determined according
to the ISDNTransferCapability parameter.
This parameter is used for the ECT/TBCT/RLT/Path Replacement ISDN
transfer methods. Usually, the device requests the PBX to connect an
incoming and outgoing call. This parameter determines if the outgoing
call (from the device to the PBX) must be connected before the transfer
is initiated.

[0] Alert = (Default) Enables ISDN Transfer if the outgoing call is in
Alerting or Connect state.

[1] Connect = Enables ISDN Transfer only if the outgoing call is in
Connect state.
Note: For RLT ISDN transfer (TrunkTransferMode = 2 and
ProtocolType = 14 DMS-100), this parameter must be set to 1.
Defines the timeout (in seconds) for determining ISDN call transfer
(ECT, RLT, or TBCT) failure. If the device does not receive any
response to an ISDN transfer attempt within this user-defined time, the
device identifies this as an ISDN transfer failure and subsequently
performs a hairpin TDM connection or sends a SIP NOTIFY message
with a SIP 603 response (depending whether hairpin is enabled or
disabled, using the parameter DisableFallbackTransferToTDM).
The valid range is 1 to 10. The default is 4.
Determines whether the device allows interworking of network-side
received ECT/TBCT Facility messages (NI2 TBCT - Two B-channel
Transfer and ETSI ECT - Explicit Call Transfer) to SIP REFER.

[0] Disable = Rejects ISDN transfer requests.

[1] Enable = (Default) The device sends a SIP REFER message to
the remote call party if ECT/TBCT Facility messages are received
