====== Global Transformation ======

===== General =====
  * See [[cucm-plus-d|+ Dialing]] for more information
  * Allow incoming call history to display the full E.164 number for callback
  * For Outgoing call to PSTN
    * External Phone Number mask - globalized the Calling Number 
    * Translation Pattern - globalized Called Party Number
    * Route Pattern to matched globalized called number and select gateway
    * Called Party Transformation - localized the Called number at the gateway
    * Calling Party Transformation - localized and Calling Number at the gateway
{{cucm-gtrans10.png|}}
  * For Incoming call from PSTN
    * Significant Digits or Translation Pattern - localized Called Number to match locally configure DN
    * Incoming Prefix - globalized calling number based on type of call
    * Calling Number Transformation Pattern - localized calling number with local offnet prefix to allow call back

===== Local Route Group =====
  * Implication of Local Route Group when combined with +Dialing
  * User can use their local dial rule
  * The number is globalized
  * A single Route Pattern \+! can be used to route to their local route group gateway

===== Configuration Outgoing Call =====
  * Global call routing (route patterns in global [E.164] format) is assumed to be in place already

==== Localized Call Ingress on Phones ====
  * **Globalize Called Number** - Translation patterns for **dialed number normalization** (globalization)
    * Match local offnet dial rule e.g. 00.! and convert called number to E.164 format
{{cucm-gtrans1.png|}}

  * **Globalize Calling Number** - External phone number masks in E.164 format for calling number normalization
{{cucm-gtrans2.png|}}

==== Localized Call Egress to Gateway ====
  * **Localized called number** - Called party global transformations for called number localization
{{cucm-gtrans3.png|}}
  * Assign Called Party Transformation to gateway.
    * If the device pool is selected, the device pool will be the preferred 
{{cucm-gtrans4.png|}}\\
**OR**
  * Configure Called Party Transformation on the device pool.
{{cucm-gtrans5.png|}}

  * **Localized calling number** - Calling party global transformation for calling number localization
{{cucm-gtrans6.png|}}
  * Assign Calling Party Transformation to gateway.
    * If the device pool is selected, the device pool will be the preferred 
{{cucm-gtrans7.png|}}\\
**OR**
  * Configure Calling Party Transformation on the device pool.

===== Configuration Inbound Call =====

==== Localized Call Ingress on Gateway ====
  * Translation patterns or significant digits for reduction of called PSTN number to internally used directory number
{{cucm-gtrans12.png|}}

  * Prefixes for calling party number normalization (globalization)
{{cucm-gtrans13.png|}}
  * If set to default, then look at next level on the device pool
{{cucm-gtrans14.png|}}
  * If again set to default, then look at the CUCM Service Parameters (Advanced Parameters)
{{cucm-gtrans15.png|}}

==== Localized Call Egress to phone ====
  * No requirements for called party number (already reduced to directory number)
  * Localized Calling Number - use Calling Party Transformation pattern
  * This allows the number display to include any local offnet dial prefix for callback
{{cucm-gtrans16.png|}}

  * Assign the Calling Party Transformation to the phone
{{cucm-gtrans17.png|}}\\
**OR**
  * Again if the device pool is set, it will be the preferred
