AudioCodes MediaPack MP-11 Series User Manual

Version 7.2 1107 Mediant 1000B Gateway & E-SBC
User's Manual 62. Configuration Parameters Reference
Parameter Description
Note: The ISDN transfer also requires that you configure the
parameter TrunkTransferMode_x to 2.
ISDN Transfer Capabilities
configure voip > interface e1-
t1|bri > isdn-xfer-cab
[ISDNTransferCapability_x]
Defines the IP-to-
ISDN Transfer Capability of the Bearer Capability IE
in ISDN Setup messages, per trunk (where the x in the ini file
parameter name denotes the trunk number and where 0 is Trunk 1).
 [-1] Not Configured
 [0] Audio 3.1 (default)
 [1] Speech
 [2] Data
 [3] Audio 7
Note: If the parameter is not configured or set to -1, Audio 3.1
capability is used.
[TransferCapabilityForDataCa
lls]
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.
ISDN Transfer On Connect
isdn-trsfr-on-conn
[SendISDNTransferOnConne
ct]
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.
configure voip > gateway
dtmf-supp-service supp-
service-settings > isdn-xfer-
complete-timeout
[ISDNTransferCompleteTime
out]
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 o
r 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.
Enable Network ISDN
Transfer
configure voip > sip-definition
settings > network-isdn-xfer
[EnableNetworkISDNTransfer
]
Determines whether the device allows interworking of network-side
received ECT/TBCT Facility messages (NI-2 TBCT - Two B-channel
Transfer and 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/TBCT Facility messages are
received from the ISDN side (e.g., from a PBX).
[DisableFallbackTransferToT
DM]
Enables "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] = (Default) The device performs a hairpin TDM transfer upon
