User's Manual 69. Configuration Parameters Reference
Parameter Description
table, see ''Configuring IP Profiles'' on page 438.
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.
[QSIGTunnelingMode] Defines the format of encapsulated QSIG message data in the SIP
message MIME body.
 [0] = (Default) ASCII presentation of Q.931 QSIG message.
 [1] = Binary encoding of Q.931 QSIG message (according to
ECMA-355, RFC 3204, and RFC 2025).
Note: The parameter is applicable only if the QSIG Tunneling feature
is enabled (using the EnableQSIGTunneling parameter).
Enable Hold to ISDN

isdn
[EnableHold2ISDN]
Enables SIP-to-ISDN interworking of the Hold/Retrieve supplementary
service.
 [0] Disable (default)
 [1] Enable
Note:
 The parameter is applicable to Euro ISDN variants - from TE (user)
to NT (network).
 The parameter is applicable to QSIG BRI.
 If the parameter is disabled, the device plays a held tone to the Tel
side when a SIP request with 0.0.0.0 or "inactive" in SDP is
received. An appropriate CPT file with the held tone should be
used.
[ISDNDuplicateQ931BuffMo
de]
Determines the activation/deactivation of delivering raw Q.931
messages.
 [0] = (Default) ISDN messages aren't duplicated.
 [128] = All ISDN messages are duplicated.
Note: For the parameter to take effect, a device reset is required.
ISDN SubAddress Format
isdn-subaddr-frmt
[ISDNSubAddressFormat]
Determines the encoding format of the SIP Tel URI parameter 'isub',
which 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] = (Default) ASCII - IA5 format that allows up to 20 digits.
Indicates that the 'isub' parameter value needs to be encoded using
ASCII characters.
 [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.
