Version 6.2
Defines the IP-to-ISDN Transfer Capability of the Bearer
Capability IE in ISDN Setup messages. The ID in the ini file
parameter depicts the trunk number, where 0 is the first trunk.
[-1] Not Configured
[0] Audio 3.1 = Audio (default).
[1] Speech = Speech.
[2] Data = Data.
Audio 7 = Currently not supported.
Note: If this parameter isn't configured or equals to '-1', Audio
3.1 capability is used.
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
Alerting 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), this parameter must be set to 1.
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 (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 Facility messages
are received from the ISDN side (e.g., from a PBX).
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.
