Sending Fax by Email - no attachment

We have an internal api that sends faxes directly from our database using php mailer. it sends both email and fax. for internal control purposes we need to continue to use this method rather than a new API just for faxes. It sends the fax / cover page, but does not send the pdf attachment.


PHP:

$fax = "111-222-3333";

$mail = new PHPMailer(true); // Passing `true` enables exceptions

$mail->SMTPOptions = array('ssl' => array('verify_peer' => false, 'verify_peer_name' => false));

$mail->CharSet = 'UTF-8';

$mail->Encoding = "base64";

try {

//Server settings

$mail->isSMTP(); // Set mailer to use SMTP

$mail->Host = 'localhost'; // Specify main and backup SMTP servers

$mail->SMTPSecure = 'tls'; // use TLS

$mail->Port = 587; // TCP port to connect to


$mail->setFrom($faxFrom);

$mail->addReplyTo($faxFrom);


$sFax2 = $fax . "@rcfax.com";

$mail->addAddress($sFax2); // Add a recipient

$mail->addAttachment($tmpfname . "_bcst.pdf", "Home Report"); // Add attachments


//Content

$sSubject = "BROADCAST " . $home->FacilityName . " - " . $client->getStrName() . " - REFID:" . $row->id; // . " - FLID:" . $fl->id;

$mail->Subject = $sSubject;

$mail->Body = " ";

$mail->isHTML(false);


$mail->send();

} catch (Exception $e) {

}

}

Can you confirm that if this is your test call on the sandbox environment or on your production environment?

Can anyone help?
This shouldn't be a sandbox vs production issue, as I am just mimicking the sending of an email. just as I can fax by sending an email to FAX#@rcfax.com from my authorized email, I should be able to send using phpmailer. for some reason RC is not parsing the multipart email the same way that other services do, but I just need to know what RC wants in the email so that I build it correctly

To be honest, I get dizzy when I look at your codes and traces. I don't see any thing related to RingCentral Fax API. I can just help you if you are using our official Fax API and here is the sample code how to send faxes using PHP language.
