23.6 Manipulating Redirected and Diverted Numbers for
Call Diversion
You can configure manipulation rules to manipulate the Diverted-to and Diverting numbers
received in the incoming Call Redirection Facility message for call diversion, which is
interworked to outgoing SIP 302 responses. This feature is applicable to the Euro ISDN
and QSIG variants, and to IP-to-Tel calls.
The incoming redirection Facility message includes, among other parameters, the
Diverted-to number and Diverting number. The Diverted-to number (i.e., new destination) is
mapped to the user part in the Contact header of the SIP 302 response. The Diverting
number is mapped to the user part in the Diversion header of the SIP 302 response.
These two numbers can be manipulated by entering the following special strings in the
'Destination Prefix' field of the Redirect Number Tel -> IP manipulation table:

"RN" - used in the rule to manipulate the Redirected number (i.e., originally called
number or Diverting number).

"DN" - used in the rule to manipulate the Diverted-to number (i.e., the new called
number or destination). This manipulation is done on the user part in the Contact
header of the SIP 302 response.
For example, assume the following required manipulation:

Manipulate Redirected number 6001 (originally called number) to 6005

Manipulate Diverted-to number 8002 (the new called number or destination) to 8005
The configuration in the Redirect Number Tel -> IP manipulation table is as follows:
