Configure Calling Party Normalization
In line with E.164 standards, calling party normalization enhances the dialing capabilities of some phones and improves call back functionality when a call is routed to multiple geographical locations; that is, the feature ensures that the called party can return a call without needing to modify the directory number in the call log directories on the phone. Additionally, calling party normalization allows you to globalize and localize phone numbers, so the appropriate calling number presentation displays on the phone.
![]() Tip |
Configuring calling party normalization alleviates issues with toll bypass where the call is routed to multiple locations over the IP WAN. In addition, it allows Cisco Unified Communications Manager to distinguish the origin of the call to globalize or localize the calling party number for the phone user. |
Before you begin
-
Review the interactions and restrictions for this feature. For more information, see topics related to globalizing the calling party number, localizing the calling party number, interactions and restrictions.
-
If you have not already done so, activate the Cisco CallManager service in Cisco Unified Serviceability. For more information, see the Cisco Unified Serviceability Administration Guide.
Procedure
Step 1 |
Perform the following steps to globalize and localize the calling party number:
|
||
Step 2 |
If you want to do so, configure the Calling Party Number Type. For more information, see topics related to globalizing the calling party number and configuring the calling party number type. |
||
Step 3 |
For incoming national, international, subscriber, and unknown calls via the PSTN, create the prefixes that you want to associate with these types of calls. You create prefixes for device types; for example, phones, MGCP gateways, H.323 gateways/trunks, SIP trunks, and so on. For more information, see topics related to globalizing the calling party number and setting the service parameters for calling party normalization. |
||
Step 4 |
If your service provider prepends leading digits (for example, a zero) to the calling party number and you want to strip these digits before prepending other digits (for example, if the leading digits are not part of the E.164 number and you want to transform the calling party number to the E.164 format), you can configure the incoming calling party number settings for device pools, gateways, and trunks to ensure that Cisco Unified Communications Manager strips the leading digits before applying the prefixes to an incoming calling party number. For more information, see topics related to applying the calling party transformation Calling Search Spaces (CSS) to localized the calling party number and incoming calling party number settings for device pools, gateways, and trunks. |
||
Step 5 |
Create various partitions for the calling party transformation patterns under .Create different partitions and calling search spaces for different calling party transformation patterns and different number types, respectively. For more information, see topics related to partition configuration settings in the Cisco Unified Communications Manager Administration Guide. |
||
Step 6 |
Create incoming calling party number calling search spaces (CSS) for the various calling party number types under . In the Calling Search Space Configuration window for the CSS, move the partition that you created for the calling party transformation pattern to the Available Partitions pane. Perform this task for each CSS that you create.You can create a CSS for the national calling party number type, a CSS for the international calling party number type, and so on. For more information, see topics related to CSS configuration settings in the Cisco Unified Communications Manager Administration Guide. |
||
Step 7 |
Choose to create the Calling Party Transformation Pattern; in the Calling Party Transformation Pattern Configuration window, assign the partition that you associated with the incoming calling party transformation CSS to the calling party transformation pattern.For more information, see topics related to calling party transformation pattern configuration settings in the Cisco Unified Communications Manager Administration Guide. |
||
Step 8 |
Choose the appropriate Incoming Calling Party Transformation CSS in the device configuration window; for example, in the Gateway Configuration, SIP Trunk Configuration, and so on.
For more information, see topics related to applying the calling party transformation CSS to localize the calling party number. The Calling Party Number is now globalized. |
||
Step 9 |
Create a partition for the calling party transformation pattern under .For more information, see topics related to partition configuration settings in the Cisco Unified Communications Manager Administration Guide. |
||
Step 10 |
Create the Calling Party Transformation calling search space (CSS) under ; in the Calling Search Space Configuration window for the calling party transformation CSS, move the partition that you created for the calling party transformation pattern to the Available Partitions pane.For more information, see topics related to CSS configuration settings in the Cisco Unified Communications Manager Administration Guide. |
||
Step 11 |
Choose to create the Calling Party Transformation Pattern; in the Calling Party Transformation Pattern Configuration window, assign the partition that you associated with the calling party transformation CSS to the calling party transformation pattern.For more information, see topics related to calling party transformation pattern configuration settings in the Cisco Unified Communications Manager Administration Guide. |
||
Step 12 |
Choose the Calling Party Transformation CSS in the device configuration window; for example, in the Gateway Configuration, Phone Configuration, Trunk Configuration, and the CTI Route Point Configuration window.
For more information, see topics related to applying the calling party transformation CSS to localize the calling party number. The Calling Party Number is now localized. |
