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 = Enables ISDN Transfer if the outgoing call is in Alert
or Connect state (default).
[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), the parameter
SendISDNTransferOnConnect must be set to 1.
Configuration 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.
Enables or disables "hairpin" TDM transfer upon ISDN (ECT,
RLT, or TBCT) call transfer failure. When this feature is enabled
and an ISDN call transfer failure occurs, the device sends a SIP
NOTIFY message with a SIP 603 Decline response.
[0] = device performs a hairpin TDM transfer upon ISDN call
transfer (default).
[1] = Hairpin TDM transfer is disabled.
Determines the encoding format of the SIP Tel URI parameter
'isub' that carries the encoding type of ISDN subaddresses. This
is used to identify different remote ISDN entities under the same
phone number - ISDN Calling and Called numbers) for
interworking between ISDN and SIP networks.
[0] = ASCII - IA5 format that allows up to 20 digits. Indicates
that the 'isub' parameter value needs to be encoded using
ASCII characters (default)
[1] = BCD (Binary Coded Decimal) - allows up to 40
characters (digits and letters). Indicates that the 'isub'
parameter value needs to be encoded using BCD when
translated to an ISDN message.
[2] = User Specified
For IP-to-Tel calls, if the incoming SIP INVITE message includes
subaddress values in the 'isub' parameter for the Called Number
(in the Request-URI) and/or the Calling Number (in the From
header), these values are mapped to the outgoing ISDN Setup
message.
If the incoming ISDN Setup message includes 'subaddress'
values for the Called Number and/or the Calling Number, these
values are mapped to the outgoing SIP INVITE message's 'isub'
parameter in accordance with RFC 4715.
