User's Manual
(in the sent ISDN Setup message). This feature is only applicable
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
1
example,
INVITE sip:9565645;isub=1234@host.domain:user=phone
SIP/2.0
then the isub value is sent in the ISDN Setup message as the
destination subaddress.
If the isub parameter is not received in the user part of the
2
Request-URI, the device searches for it in the URI parameters of
the To header, for example,
To: "Alex" <sip: 9565645@host.domain;isub=1234>
If present, the isub value is sent in the ISDN Setup message as
the destination subaddress.
If the isub parameter is not present in the Request-URI header
3
nor To header, the device does the following:

If the called number (that appears in the user part of the
Request-URI) starts with zero (0), for example,
INVITE sip:05694564@host.domain:user=phone SIP/2.0
then the device maps this called number to the destination
number of the ISDN Setup message, and the destination
subaddress in this ISDN Setup message remains empty.

If the called number (that appears in the user part of the
Request-URI) does not start with zero, for example,
INVITE sip:5694564@host.domain:user=phone SIP/2.0
then the device maps this called number to the destination
number of the ISDN Setup message, and the destination
subaddress in this ISDN Setup message then contains y
digits from the end of the called number. The y number of
digits can be configured using the ISUBNumberOfDigits
parameter. The default value of ISUBNumberOfDigits is 0,
thus, if this parameter is not configured, and 1) and 2)
scenarios (described above) have not provided an isub
value, the subaddress remains empty.
Defines a single default ISDN release cause that is used (in ISDN-
to-IP calls) instead of all received release causes, except when the
following Q.931 cause values are received: Normal Call Clearing
(16), User Busy (17), No User Responding (18), or No Answer from
User (19).
The range is any valid Q.931 release cause (0 to 127). The default
is 0 (i.e., not configured - static mapping is used).
Enables the mapping of the calling party category (CPC) between
the incoming PSTN message and outgoing SIP message, and vice
versa (i.e., for IP-to-Tel and Tel-to-IP calls). The CPC characterizes
the station used to originate a call (e.g., a payphone or an
operator).

[0] Disable = (Default) CPC is not relayed between SIP and
PSTN.

[1] Enable
The CPC is denoted in the PSTN message as follows:

ISDN PRI NI-2: In the Originating Line Information (OLI)
Information Element (IE) of the ISDN Setup message.
