Version 6.8
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).

This 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.
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 this parameter to take effect, a device reset is required.
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.
Determines whether the device ignores the Subaddress from the
incoming ISDN Called and Calling numbers when sending to IP.

[0] = (Default) If an incoming ISDN Q.931 Setup message
contains a Called/Calling Number Subaddress, the Subaddress
is interworked to the SIP 'isub' parameter according to RFC.

[1] = The device removes the ISDN Subaddress and does not
include the 'isub' parameter in the Request-URI and does not
process INVITEs with this parameter.
Defines the number of digits (from the end) that the device takes
from the called number (received from the IP) for the isub number
