It Depends If We Have the Phone Number of their New Account in Our Companies Database
Whenever we detect a job change for a contact, we'll give you the option to update their account to reflect their new job, and if you do:
1. If we have the corporate phone number for the new company/account, we'll replace the current corporate phone number listed for that Contact with the updated phone number.
Important Note: This update will push to your Salesforce instance to reflect the new corporate phone number for the company/account.
2. If we don't have the corporate phone number for the company/account, we'll keep the current corporate phone number but mark its status as "Invalid" (Red) to indicate that the phone number is no longer valid for the contact.
The same exact logic applies to Direct Work Phone Numbers. It does NOT apply to Mobile or Home numbers, as we assume Contacts don't usually change those when they change jobs.
