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 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.
https://developers.ringcentral.com/guide/messaging/fax/sending-faxes#php
as I mentioned at the beginning, I need to try and keep the 2 fax services as close as possible in how the fax is sent.
You can ignore the trace, I only added it to show the actual email transaction with the email server.
The php code is about as simple as it gets. It sets a few options, sets a TO: and FROM:, adds the PDF and sends it. PHPMailer is simply sending an email to fax#@rcfax.com, however when RC sends the fax it only sends the cover page. I suspect that it has something to do with how the multipart email is being parsed by RC as opposed to FF.
However here is a stripped down version of the Mailer code:
$mail = new PHPMailer();
try {
$mail->setFrom("fax@ca********nt.com");
$mail->addAddress("1112223333@rcfax.com");
$mail->addAttachment("report.pdf", "Report");
$mail->Subject = "Fax From Peter";
$mail->Body = " ";
$mail->send();
} catch (Exception $e) { }
production
Can you confirm that if this is your test call on the sandbox environment or on your production environment?
Change $mail->addAttachment("report.pdf", "Report");
to $mail->addAttachment("report.pdf", "report.pdf");
And try again.
Make sure you always specify the file extension .
PS. The solution was figured out by my colleague Kirill Tikhonov.
Thank you very much that resolved it. Our last solution didn't require the extension and allowed us to use a screen friendly name.
