Unable to remove phone number from person

Hello we are attempting to remove the primary number from a person so that they would go back to only have an extension but are getting the following error:

            "primary": true,
            "action": "DELETE",

    ]
}

I read this page that said you can use the update person API to remove a primary number from a user but no details on how to pass the object to remove the primary number. https://developer.webex.com/docs/api/v1/people/update-a-person

In Control Hub you have the ability to remove a primary number and the person reverts back to only having an extension. How can we accomplish this through the API so that they no longer have a primary number but only an extension?

Hi @joedeveloper- ,

With this API method, you cannot assign or unassign Primary Number. This method is only used for Alternate Phone Numbers. It is mentioned in description:

Hi buddy,

Typically, to remove a primary number and revert to using only an extension, you might need to assign a new primary number or set a different number as the primary one. After doing so, you can then remove the original primary number.
