Parameter Description
Note:
This capability is applicable only to the NI-2 ISDN variant.
[EarlyAnswerTimeout]
Global parameter that defines the duration (in seconds) that the device
waits for an ISDN Connect message from the called party (Tel side),
started from when it sends a Setup message. You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_EarlyAnswerTimeout). For a detailed description of the
parameter and for configuring this functionality in the IP Profile table, see
''Configuring IP Profiles'' on page 391.
Note:
If this functionality is configured for a specific IP Profile, the settings
of this global parameter is ignored for calls associated with the IP Profile.
Trunk Transfer Mode
[TrunkTransferMode]
Determines the trunk transfer method (for all trunks) when a SIP REFER
message is received. The transfer method depends on the Trunk's PSTN
protocol (configured by the parameter ProtocolType) and is applicable
only when one of these protocols are used:
PSTN Protocol Transfer Method (Described Below)
E1 Euro ISDN [1] ECT [2] or InBand [5]
E1 QSIG [21],
T1 QSIG [23]
Single Step Transfer [4], Path
Replacement Transfer [2], or InBand [5]
T1 NI2 ISDN [10],
T1 4ESS ISDN [11],
T1 5ESS 9 ISDN [12]
TBCT [2] or InBand [5]
T1 DMS-100 ISDN [14] RTL [2] or InBand [5]
T1 RAW CAS [3], T1
CAS [2], E1 CAS [8], E1
RAW CAS [9]
[1] CAS NFA DMS-100 or [3] CAS Normal
transfer
T1 DMS-100 Meridian
ISDN [35]
RTL [2] or InBand [5]
The valid values of the parameter are described below:
 [0] = Not supported (default).
 [1] = Supports CAS NFA DMS-100 transfer. When a SIP REFER
message is received, the device performs a Blind Transfer by
executing a CAS Wink, waits for an acknowledged Wink from the
remote side, dials the Refer-to number to the switch, and then
releases the call.
Note: A specific NFA CAS table is required.
 [2] = Supports ISDN transfer - Release Link Trunk (RLT) (DMS-100),
Two B Channel Transfer (TBCT) (NI2), Explicit Call Transfer (ECT)
(EURO ISDN), and Path Replacement (QSIG). When a SIP REFER
message is received, the device performs a transfer by sending
Facility messages to the PBX with the necessary information on the
call's legs to be connected. The different ISDN variants use slightly
different methods (using Facility messages) to perform the transfer.
Notes:

For RLT ISDN transfer, the parameter
SendISDNTransferOnConnect must be set to 1.

The parameter SendISDNTransferOnConnect can be used to
define if the TBCT/ECT transfer is performed after receipt of
Alerting or Connect messages. For RLT, the transfer is always
