
[1] = The device removes the ISDN Subaddress and does not
include the 'isub' parameter in the Request-URI and does not
process INVITEs with this 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 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 example,
1
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
3
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).
This table parameter maps ISDN Q.850 Release Causes to SIP
responses.
The format of this parameter is as follows:
[CauseMapISDN2SIP]
FORMAT CauseMapISDN2SIP_Index =
CauseMapISDN2SIP_IsdnReleaseCause,
