Note: The parameter is applicable only to the NI-2 ISDN variant.
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 Profiles table,
see 'Configuring IP Profiles' on page 405.
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.
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
E1 Euro ISDN [1]
E1 QSIG [21],
T1 QSIG [23]
T1 NI2 ISDN [10],
T1 4ESS ISDN [11],
T1 5ESS 9 ISDN [12]
T1 DMS-100 ISDN [14]
T1 RAW CAS [3], T1
CAS [2], E1 CAS [8], E1
RAW CAS [9]
T1 DMS-100 Meridian
ISDN [35]
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 PRI/BRI 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
