Set default Caller phone number field to a specific region on IMS Interaction Record

[Xavier_Wharton]

Hello Community, 

I need help configuring the dictionary entry for the 'caller_phone_number' field on the IMS record. 
Please review the information below and let me know if you have any questions. 

I want to set the field's default value to "North America." 

I have tried two different approaches, but with no luck:
1. Typing the Default Value field to North America
2. Changing the Attributes field to "phone_number_default_region=US"

I was able to make it work using a Client Script (onLoad). 
I made a video with some additional context that you can click the link below:

Steps to reproduce:

1. Show the "Caller Phone Number" field on the following form views:
   
   • Default
   • Service Operations Workspace
   • Service Operations Workspace New Record
2. Navigate to All > System Definition > Client Scripts
3. Click the "New" button on the top right
4. Enter the following in the fields on the new record:
   • Name: Set Default Phone Region to [InsertRegion]
   • Table: Interaction [interaction]
   • UI Type: All - Unless you want only Desktop or only Mobile
   • Type: onLoad
   • Active: True ☑️
   • Global: True ☑️
   • Description: 
     

     Sets the default value of the Caller Phone Number field (+1) for new Interaction records to simulate a North America default region for E.164 phone format.

   • Script:
     

function onLoad() {
    if (g_form.isNewRecord()) {
        var currentValue = g_form.getValue('caller_phone_number');
        if (!currentValue) {
            // Set default country code to +1 for North America (US).
            // Replace "+1" with your region's country code if different.
            g_form.setValue('caller_phone_number', '+1');
        }
    }
}
