Table 6-51: Number Manipulation Parameters

Determines whether the device copies the
called number to the outgoing SIP Diversion header for
Tel-to-IP calls (even if a Redirecting Number IE is not
received in the ISDN Setup message)
called number is used as a redirect number. Call
redirection information is typically used for Unified
Messaging and voice mail services to identify the recipient
of a message.

[0] Don't copy = Disable (default).

[1] Copy after phone number manipulation = Copies the
called number after manipulation. The device first
performs Tel-to-IP destination phone number
manipulation (i.e., on the SIP To header), and only then
copies the manipulated called number to the SIP
Diversion header for the Tel-to-IP call. Therefore, with
this option the called and redirected numbers are
identical.

[2] Copy before phone number manipulation = Copies
the called number before manipulation. The device first
copies the original called number to the SIP Diversion
header, and then performs Tel-to-IP destination phone
number manipulation. Therefore, this allows you to have
different numbers for the called (i.e., SIP To header)
and redirected (i.e., SIP Diversion header) numbers.
Notes:

If the incoming ISDN-to-IP call includes a Redirect
Number, this number is overridden by the new called
number if this parameter is set to [1] or [2].

This parameter can also be configured for IP Profiles
(using the parameter IPProfile).
Determines whether the received Phone-Context
parameter is added as a prefix to the outgoing
SETUP message with

[0] Disable = Disable (default).

[1] Enable = Enable.
This ini file table parameter defines the Phone Context
table. This parameter maps NPI and TON to the SIP
Phone-Context parameter. When a call is received from
the ISDN, the NPI and TON are compared against the
table and the Phone-Context value is used in the outgoing
SIP INVITE message. The same mapping occurs when an
INVITE with a Phone-Context attribute is received. The
