How can we verify phone number with Twilio account in Salesforce Apex?

I have gone the answer for this by myself.

First Checkout or download the Twilio-salesforce library from GitHub. Then, deploy the code into Salesforce org

Search the phone number to buy from Twilio - account with following code:

String ACCOUNT_SID = 'AXXXXXXXXXXXXXXXXX';
String AUTH_TOKEN = 'YYYYYYYYYYYYYYYYYY';
TwilioRestClient client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN);
List<TwilioAvailablePhoneNumbers> numbers;
Map<String,String> filters = new Map<String,String> {
'AreaCode' => '530'
};
numbers = client.getAccount().getAvailablePhoneNumbers(filters).getPageData();
if (numbers.isEmpty()) {
System.debug('No numbers in 530 available');
} else {
numbers[0].purchase();
}

With following code you can buy phone number with Twilio account in Salesforce Apex

String ACCOUNT_SID = 'AXXXXXXXXXXXXXXXXX';
String AUTH_TOKEN = 'YYYYYYYYYYYYYYYYYY';
TwilioRestClient client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN);
TwilioIncomingPhoneNumber incoming;
Map<String,String> properties =
new Map<String,String>{'PhoneNumber' => '+15305431234'};
incoming = client.getAccount().getIncomingPhoneNumbers().create(properties);

For more reference, you can refer Twilio-document.

Hi Archit,

You understood the question wrong.

The code you provide is to make a call with Twilio but my question is to verify phone number with Twilio account in Salesforce Apex.
