# Missing Phone Number
RIS-RM-1029 MissingPhoneNumber
The Missing *Phone Number* application contains a macro that runs as the [*Rules Engine*](https://docs.linnworks.com/articles/documentation/rules-engine-actions)[ action](https://docs.linnworks.com/articles/documentation/rules-engine-actions). This macro automatically fills in the shipping address phone number in the order details with the default one from the preset configuration if it was initially empty.
This guide provides a step-by-step explanation of how to install and set up the macro in Linnworks.
### Start using the macro
There are three steps you need to complete to start using the macro:
1. Install the application.
* Go to *Apps > Application Store >* Missing *Phone Number >* click Install and follow the on-screen instructions until the installation is complete.
2. Configure the macro.
3. Configure the rule in the *Rules Engine* screen.
#### Configure the macro
Once the Missing *Phone Number* app is installed:
1. Go to *Apps > Macro Configuration* and click + Add new configuration.
2. Select the Missing *Phone Number* macro and click Create Configuration.
3. In the *Macro Configuration* screen, specify the below details and click *Save*:
* Configuration name (*required*): The name of the configuration. This field is required; without it, the system will not allowed to save the configuration.
* Default phone number (*required*): In the *Value* field, specify the default phone number to be added to orders with the shipping address phone number initially empty.
4. Make sure to enable the macro to continue with the *Rules Engine* configuration.
**Functionality:**
1. **Identify Orders**: The macro takes a list of OrderIds as input to identify orders with missing phone numbers.
2. **Default Phone Number**: It also takes a default phone number as input, which will be used to fill in missing phone numbers.
3. **Rules Engine**: The macro operates within a rules engine or scheduling system to regularly check for orders with missing phone numbers.
4. **Processing Logic**: For each order in the provided list, the macro checks if a phone number is missing.
5. **Update Phone Number**: If a phone number is missing, the macro updates the order with the default phone number provided.
6. **Logging and Notifications**: It logs actions taken, such as orders processed and phone numbers updated. Notifications can be implemented to alert administrators or users about orders that were updated.
**Usage:**
* **Parameters:**
* `OrderIds`: List of OrderIds for which phone numbers need to be checked and updated.
* `DefaultPhoneNumber`: Default phone number to be used for orders with missing phone numbers.
* **Execution:**
* The macro is executed within a rules engine or scheduled system at predefined intervals.
* It takes the list of OrderIds and the default phone number as parameters.
* The macro iterates through the provided list of orders, checks for missing phone numbers, and updates them if necessary.
* **Outcome:**
* Orders that originally had missing phone numbers now have the default phone number associated with them.
* The macro ensures that all orders have valid phone numbers, which is crucial for communication and shipping purposes.
* Logs and notifications provide transparency and allow administrators to track the actions taken by the macro.
