Configuring Redirect Number Manipulation

Each redirect number manipulation table lets you configure up to 20 rules for manipulating the
redirect number received in SIP messages. The redirect number manipulation tables include:
■ Redirect Number IP-to-Tel table: (Applicable only to ISDN) Defines IP-to-Tel redirect number
manipulation. You can manipulate the value of the received SIP Diversion, Resource-Priority,
or History-Info headers, which is then added to the Redirecting Number Information Element
(IE) in the ISDN Setup message sent to the Tel side. This also includes the reason for the call
redirection.
■ Redirect Number Tel-to-IP table: Defines Tel-to-IP redirect number manipulation. You can
manipulate the prefix of the redirect number received from the Tel side, in the outgoing SIP
Diversion, Resource-Priority, or History-Info headers sent to the IP side.
Configuration of redirect number manipulation rules includes two areas:
■ Match: Defines the matching characteristics of an incoming call (e.g., prefix of redirect
number).
■ Action: Defines the action that is done if the incoming call matches the characteristics of the
rule (e.g., removes a user-defined number of digits from the left of the redirect number).
The device searches the table from top to bottom for the first rule that matches the
characteristics of the incoming call. If it finds a matching rule, it applies the manipulation configured
for that rule.

The following procedure describes how to configure redirect number manipulation rules through the
Web interface. You can also configure these rules using the following management tools:
■ Redirect Number IP-to-Tel table: ini file [RedirectNumberMapIp2Tel] or CLI (configure
voip > gateway manipulation redirect-number-map-ip2tel)
■ Redirect Number Tel-to-IP table: ini file [RedirectNumberMapTel2Ip] or CLI (configure
voip > gateway manipulation redirect-number-map-tel2ip)
Defines the number or string to add at the front of the calling
name.
For example, if you enter ITSP and the calling name is
"company:name", the new name is ITSPcompany:john".
Defines the number or string to add at the end of the calling
name.
For example, if you enter 00 and calling name is
"company:name", the new name is "company:name00".
If the device copies the received destination number to the outgoing SIP redirect
number (enabled by the CopyDest2RedirectNumber parameter), no redirect
number Tel-to-IP manipulation is done.
The manipulation rules are done in the following order: 'Stripped Digits From Left',
'Stripped Digits From Right', 'Number of Digits to Leave', 'Prefix to Add', and then
'Suffix to Add'.
The device uses the 'Redirect Prefix' parameter before it manipulates the prefix.
