Sending a fax does not work when you have attachments I have the following problem:I am using the code for sending a fax as it is published in the official documentation.// Send Fax
$request = $rcsdk->createMultipartBuilder()
->setBody(array(
'to' => array(
array('phoneNumber' => xxxxxxxxxxxxx),
),
'faxResolution' => 'High',
))
->add('Plain Text', 'file.txt')
->add(fopen('https://developers.ringcentral.com/assets/images/ico_case_crm.png', 'r'))
->request('/account/~/extension/~/fax');
//print $request->getBody() . PHP_EOL;
$response = $platform->sendRequest($request);
print 'Sent Fax ' . $response->json()->uri . PHP_EOL;This works perfectly for me in my local development environment. (
