Twilio lookup test numbers
<p><a href="https://www.twilio.com/docs/api/rest/test-credentials#test-sms-messages-parameters-To" rel="nofollow noreferrer">There are test numbers</a> to which you can send SMS using <a href="https://www.twilio.com/user/account/phone-numbers/dev-tools/test-credentials" rel="nofollow noreferrer">my test credentials</a>. They fake sending beautifully. But, attempting to use the <a href="https://www.twilio.com/docs/api/lookups#lookups-query-parameters" rel="nofollow noreferrer">lookup API</a> also provided by Twilio, even if the intention is to retrieve information about the <a href="https://stackoverflow.com/questions/23024936/test-telephone-numbers-for-twilio">test number</a>, will fail:</p>

TwilioRestException: 
HTTP Error Your request was:

</code></pre>

<p>+15005555009 is the only phone number listed to emulate a landline, that is incapable of returning an SMS. I am expecting the API to return 'landline' for the carrier type for such a number. <a href="https://www.twilio.com/docs/errors/20008" rel="nofollow noreferrer">That link in the error message</a> brings me to a page with no working test credentials.</p>

<p>How can I test the lookup API with the test credentials given?</p>
