✔
Tel-to-IP (network side): When a Facility message
initiating an out-of-band blind transfer is received from
the PBX, the device sends a SIP REFER message to
the IP side (if the EnableNetworkISDNTransfer
parameter is set to 1).
Note: To configure trunk transfer mode per trunk, use the
parameter TrunkTransferMode_x.
Determines the trunk transfer mode per trunk (where x denotes
the Trunk number). To configure trunk transfer mode for all
trunks and for a description of the parameter options, refer to the
parameter TrunkTransferMode.
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 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.
The 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. The
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), the 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.
