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 Request-
2
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 nor To
3
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 the 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.

MFC-R2: ANI II digits. The device supports the Brazilian and
Argentinian variants. This regional support is configured using the
CallingPartyCategoryMode.
The CPC is denoted in the SIP INVITE message using the 'cpc='
parameter in the From or P-Asserted-Identity headers. For example, the
'cpc=' parameter in the below INVITE message is set to "payphone":
INVITE sip:bob@biloxi.example.com SIP/2.0
To: "Bob" <sip:bob@biloxi.example.com>
From: <tel:+17005554141;cpc=payphone>;tag=1928301774
