Determines the bit map for special PSTN behavior
parameters:

[0] = (Default) Applicable for NI-2 ISDN and QSIG
"Networking Extensions". This bit (i.e., bit #0) is
responsible for the Invoke ID size:

If this bit is not set (default), then the Invoke ID size
is always one byte, with a value of 01 to 7f.

If this bit is set, then the Invoke ID size is one or two
bytes according to the Invoke ID value.

[2] = Applicable to the ROSE format (according to the old
QSIG specifications). This bit (i.e., bit #1) is responsible
for the QSIG octet 3. According to the ECMA-165 new
version, octet 3 in all QSIG supplementary services
Facility messages should be 0x9F = Networking
Extensions. However, according to the old version, the
value should be 0x91 = ROSE:

If this bit is not set (default): 0x9F = Networking
Extensions.

If this bit is set: 0x91 = ROSE.

[3] = Use options [0] and [2] above.
Note: For this parameter to take effect, a device reset is
required.
Determines the device's handling of the date and time sent in the
ISDN Connect message (Date / Time IE) upon receipt of SIP 200
OK messages.

[0] Disable = (Default) If the SIP 200 OK includes the Date
header, the device sends its value in the ISDN Connect Date /
Time IE. If the 200 OK does not include this header, it does not
add the Date / Time IE to the sent ISDN Connect message.

[1] Enable = If the SIP 200 OK includes the Date header, the
device sends its value (i.e. date and time) in the ISDN Connect
Date / Time IE. If the 200 OK does not include this header, the
device uses its internal, local date and time for the Date / Time
IE, which it adds to the sent ISDN Connect message.

[2] Always Send Local Date and Time = The device always
sends its local date and time (obtained from its internal clock) to
PBXs in ISDN Q.931 Connect messages (Date / Time IE). It
does this regardless of whether or not the incoming SIP 200 OK
includes the Date header. If the SIP 200 OK includes the Date
header, the device ignores its value.
Notes:

This feature is applicable only to Tel-to-IP calls.

For IP-to-Tel calls, this parameter is not applicable. Only if the
