SIP User's Manual
For example:
CauseMapSIP2ISDN 0 = 480,50;
CauseMapSIP2ISDN 0 = 404,3;
When a SIP response is received (from the IP side), the
device searches this mapping table for a match. If the SIP
response is found, the Q.850 Release Cause assigned to it is
sent to the PSTN. If no match is found, the default static
mapping is used.
Notes:

This parameter can appear up to 12 times.

For an explanation on ini file table parameters, refer to
''Format of ini File Table Parameters''
Determines the Q.850 cause value specified in the Reason
header that is included in a 4xx response when Special
Information Tone (SIT) is detected on an IP-to-Tel call.
The valid range is 0 to 127. The default value is 34.
Determines whether Calling Party Category (CPC) is mapped
between SIP and PRI.

[0] Disable = Don't relay the CPC between SIP and PRI
(default).

[1] Enable = The CPC is relayed between SIP and PRI.
If enabled, the CPC received in the Originating Line
Information (OLI) IE of an incoming ISDN SETUP message is
relayed to the From / P-Asserted-Identity headers using the
'cpc' parameter, in the outgoing INVITE message, and vice
versa.
For example (calling party is a payphone):
From:<sip:2000;cpc=payphone@10.8.23.70>;tag=1c1806157
451
Note: This feature is supported only when using the NI-2 PRI
variant.
Determines the format of the User-to-User SIP header in the
INVITE message for interworking the ISDN User to User
Information Element (UU IE) data to SIP.

[0] = Format: X-UserToUser (default).

[1] = Format: User-to-User with Protocol Discriminator (pd)
attribute.

d=4. (This format is according to "draft-johnston-sipping-cc-
uui-04".)

and pd embedded as the first byte.
