Parameter Description
(in addition to the QSIG protocol).

For more information on QSIG tunneling, see 'QSIG Tunneling' on
page
312 .
[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: This parameter is applicable only if the QSIG Tunneling feature is
enabled (using the EnableQSIGTunneling parameter).
Web: Enable Hold to
ISDN
EMS: Enable Hold 2
ISDN
[EnableHold2ISDN]
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 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.
EMS: Duplicate Q931
Buff Mode
[ISDNDuplicateQ931Bu
ffMode]
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.
Web/EMS: ISDN
SubAddress Format
[ISDNSubAddressForm
at]
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.
[IgnoreISDNSubaddres
s] 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.
