Version 6.8
ISDNDuplicateQ931BuffMode to 128 (i.e., duplicate all
messages).

ISDN tunneling is applicable for all ISDN variants as well as
QSIG.
Enables ISDN Tunneling for IP-to-Tel calls.

[0] Disable (default)

[1] Enable ISDN Tunneling from IP to ISDN
When ISDN Tunneling is enabled, the device extracts raw data
received in the proprietary SIP header, x-isdntunnelinginfo, or a
dedicated message body (application/isdn) in the SIP message and
then sends the data in an ISDN message to the PSTN.
If the raw data in this SIP header is suffixed with the string "ADDE",
then the raw data is extracted and added as Informational Elements
(IE) in the outgoing Q.931 message. The tunneling of the x-
isdntunnelinginfo SIP header with IEs is converted from INVITE,
180, and 200 OK SIP messages to Q.931 SETUP, ALERT, and
CONNECT respectively.
For example, if the following SIP header is received,
x-isdntunnelinginfo: ADDE1C269FAA 06
800100820100A10F020136 0201F0A00702010102021F69
then it is added as an IE to the outgoing Q.931 message as
1C269FAA 06 800100820100A10F020136
0201F0A00702010102021F69, where, for example, "1C269F" is a
26 byte length Facility IE.
Note: This feature is similar to that of the AddIEinSetup parameter.
If both parameters are configured, the x-isdntunneling parameter
takes precedence.
Global parameter that enables QSIG tunneling-over-SIP for all calls.
You can also configure this functionality per specific calls, using IP
Profiles (IpProfile_EnableQSIGTunneling). For a detailed
description of this parameter and for configuring this functionality in
the IP Profile table, see ''Configuring IP Profiles'' on page 300.
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.
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: This parameter is applicable only if the QSIG Tunneling
feature is enabled (using the EnableQSIGTunneling parameter).
Enables SIP-to-ISDN interworking of the Hold/Retrieve
supplementary service.

[0] Disable (default)

[1] Enable
Notes:

This parameter is applicable to Euro ISDN variants - from TE
(user) to NT (network).

If the parameter is disabled, the device plays a held tone to the
