Modified on October 10, 2021

  1. Sending a fax involves you setting up a few settings first. First ensure that you have signed up for a Kiwi VoIP fax number following steps 1 and 2 above in the ‘receiving’ section. Then login to Kiwi VoIP Portal at and bring up your fax settings for your number. Next click on ‘Faxmail Sending Options’.
  2. In the Faxmail Sending Options page you can specify which email addresses are allowed to send faxes via this number. You can enter multiple email addresses here. If you do not enter the email address(es) correctly then faxes will not be allowed to be sent from these email addresses.
  3. You can also specify how many times Kiwi VoIP should retry sending a fax and the number of minutes to wait between retries. If you wish you can also request that all fax messages should include a fax verification passphrase in the Subject line for added security. This can be any phrase and the system will check that this phrase exists anywhere in the Subject header when accepting a faxmail.
  4. Now the system has been instructed to allow faxes from your email address(es) you simply attach your document to an email. Documents can be in PDF, Postscript (.PS) or TIFF formats. Most computers should allow you print your document to a Postscript file by ticking the ‘Print to File’ box when printing your document. This will create a .ps (Postscript) file which you can then attach to an email and send to the Kiwi VoIP faxmail service.
  5. One you have attached your PDF, PS or TIFF file, your email should be sent to the phone For example if you wanted to fax the document to ‘099749000′ you would send the email to ‘‘. You can fax the document to multiple fax numbers by simply adding multple recepients to your email.
  6. Once you are ready, then hit Send and your attachment should be sent to the phone numbers specified as recipients. Our Kiwi VoIP faxmail service should send you an email when the fax has been sent confirming the delivery and details. You will also receive an email with the relevant details if the fax fails to be sent for some reason.

If you are having problems sending or receiving a fax then please ensure that the other fax machine you are sending/receiving from is switched on and working corrrectly. Failing this please contact for assistance.
