question

Thank you for the reply Mike. Just tried your suggestion. Still not working.

Hi TJ,

Here's is a list of the most common reasons that a fax might fail.  What method are you using to send the fax? email, softphone, mobile app, print to fax, etc? 




Common Causes of Fax Failures

Below are the tips on checking the causes of fax failures.  It is important to follow the guidelines to avoid these errors:

Email to Fax

When trying to send faxes through email, make sure that you add email addresses permitted to send faxes.  You can only send faxes from your trusted addresses.
The file size of the document should be less than 20 MB.
Send the fax using this format @rcfax.com.

Internet Connection Make sure that your device is connected to the Internet.  RingCentral uses the Internet to send data.
Make sure that the firewall is on both the sender and the receiver's end are configured to send/receive faxes.

File Attachment Make sure that the attached document is not corrupt.  If unable to send the fax, try attaching another file and then send.

Ensure that the document is a supported file attachments for faxes.
When documents go beyond the printable area, it may be best to resize them using your PDF viewer at around 90-95%.
The filename of your fax attachments should not include ampersands (e.g. &) or other special characters for you to able to send it.

Hi TJ,  Just checking in to see if you are still having problems sending faxes? 

Try renaming the pdf file.  If there are any special characters remove those to. Might be a formatting issue in the file name.
