User's Manual

[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 redirect 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 redirect (i.e., SIP Diversion header) numbers.
Note:

If the incoming ISDN-to-IP call includes a Redirect Number, this
number is overridden by the new called number if the parameter
is set to [1] or [2].

You can also use this feature for IP-to-Tel calls, by configuring
the parameter per IP Profile
(IpProfile_CopyDest2RedirectNum). For more information, see
Configuring IP Profiles on page 438.
Enables the replacement of the calling number with the redirect
number for ISDN-to-IP calls.

[0] = Disable (default)

[1] = The calling name is removed and left blank. The outgoing
INVITE message excludes the redirect number that was used to
replace the calling number. The replacement is done only if a
redirect number is present in the incoming Tel call.

[2] = Manipulation is done on the new calling party number
(after manipulation of the original calling party number, using the
Tel2IPSourceNumberMappingDialPlanIndex parameter), but
before the regular calling or redirect number manipulation:

If a redirect number exists, it replaces the calling party
number. If there is no redirect number, the calling number is
left unchanged.

If there is a calling "display" name, it remains unchanged.

The redirect number remains unchanged and is included in
the SIP Diversion header.
Determines whether the Trunk Group ID is added as a prefix to the
destination phone number (i.e., called number) for Tel-to-IP calls.

[0] No = (Default) Don't add Trunk Group ID as prefix.

[1] Yes = Add Trunk Group ID as prefix to called number.
Note:

This option can be used to define various routing rules.

To use this feature, you must configure the Trunk Group IDs
(see Configuring Trunk Groups on page 501).
Defines if the port number/Trunk ID is added as a prefix to the
called (destination) number for Tel-to-IP calls.

[0] No (Default)

[1] Yes
If enabled, the device adds the following prefix to the called phone
number: port number/Trunk ID (single digit in the range 1 to 8).
