How to validate phonenumber in Docusign Phone authentication

Question

I have implemented Docusign Remote Signing Process and added phone authentication by setting identity verification for signer

signer.setIdentityVerification(recipientIdentityVerification());


public RecipientIdentityVerification recipientIdentityVerification() throws IOException, ApiException 
{
        RecipientIdentityPhoneNumber phoneNumber = new RecipientIdentityPhoneNumber();
        phoneNumber.setCountryCode("+1");
        phoneNumber.setNumber("**********");

        RecipientIdentityInputOption inputOption = new RecipientIdentityInputOption();
        inputOption.setName("phone_number_list");
        inputOption.setValueType("PhoneNumberList");
        inputOption.setPhoneNumberList(Arrays.asList(phoneNumber));

        RecipientIdentityVerification identityVerifcation = new RecipientIdentityVerification();


        identityVerifcation.setWorkflowId(getWorkflowID());
        identityVerifcation.setInputOptions(Arrays.asList(inputOption));
        return identityVerifcation;

    }

Now if we give 10 digit random number, it throws an error code PHONE_NUMBER_INVALID with message Phonenumber is not valid. It only accepts genuine number for which we can get OTP. How to achieve this validation in my app. How can I validate phone numbers entered by our clients?

Yes, DocuSign validates the phone number. Not just the format, but also to ensure, for example, that the area code is valid and the phone number is valid (like a number doesn't start with 0 or 1 for example).

To validate the numbers yourself:

On client - https://www.npmjs.com/package/react-phone-number-input
On server - https://github.com/google/libphonenumber

The server validation above is more thorough and checks more things.
