Enables SIP-to-ISDN interworking of the Hold/Retrieve supplementary
service.

[0] Disable (default)

[1] Enable
Notes:

The 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 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 the 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 the 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 (in the sent
ISDN Setup message). This feature is applicable only for IP-to-ISDN
calls.
The valid value range is 0 to 36. The default is 0.
This feature operates as follows:
If an isub parameter is received in the Request-URI, for example,
