GreenFax Frequently Asked Questions
Do I need to install special software on my system to receive faxes through GreenFax?
No. If you can receive email and open PDF files (or TIFF files), then you need nothing more to start using GreenFax.
How do I open and/or print faxes that I receive through GreenFax?
GreenFax offers the option to receive inbound faxes either in PDF format or TIFF format. Faxes received in PDF format can be opened and printed using Adobe Reader, which is available free of charge from Adobe, Inc. Faxes received in TIFF format can generally be opened and printed on most Microsoft Windows systems using software included with Windows.
I receive sensitive/confidential information via fax. Does GreenFax offer a secure method for receiving faxes?
Yes. See information about receiving inbound faxes securely in our user guide.
I am an application developer, and I am developing a system that process inbound faxes. Is it possible to integrate my system with GreenFax for processing inbound faxes?
Yes. Please see our inbound fax integration guide for more info.
I would like to have my inbound faxes forwarded to multiple email recipients. Is this possible?
Yes. You can add up to five email addresses to your account. To add additional email addresses to your account, login to your account at the GreenFax web site, and then click 'account preferences'.
I am getting postscript errors or experiencing printing problems when trying to print PDF files that I receive through GreenFax. What might be the problem?
Please see Adobe's guide for troubleshooting printing problems.
Is it necessary for senders to dial the area code when sending faxes to my GreenFax number, if the sender is calling from within the same area code?
The answer to this question varies from region to region, and is determined by the carrier that the sender is using for their local telephone service. In some cases, it may be possible to connect to a GreenFax number simply by dialing just the 7 digit number, without the area code, if the sender is located within the same area code. However, it is becoming increasingly common for carriers to require callers to dial a 1, followed by the 10 digit area code and phone number, even for calls within the same area code. The reasons for this stem from area code overlays in most major metropolitan areas that have become prevalent in the last decade, in addition to deregulation which has resulted in multiple competing carriers that compete within the same area code. If a sender is experiencing a busy signal or recorded error message when attempting to connect to a GreenFax number dialing only 7 digits, the sender should try again dialing a 1, followed by the 10-digit area code and fax number.
I have been receiving junk faxes to my GreenFax number. Is GreenFax selling my fax number to fax spammers?
Unfortunately, the problem of junk faxes is as much of a problem in virtual faxing as it is with conventional fax machines. We absolutely do not disclose to any third parties the fax numbers that we provide to our clients. However, fax spammers are able to build lists of thousands of fax numbers very inexpensively using automated dialing systems that detect fax signals, as well as other methods.
Although this is problem that we have no control over, junk faxes are illegal, and the FTC and FCC have handed down a number of significant fines to offenders recently. Also, most states have laws banning unsolicited faxing. You may want to visit junkfaxes.org for more information, including links to various state and federal web sites where you can report the junk faxes that you have received.
How can I annotate (or add my signature) to faxes that I receive through GreenFax?
If you are receiving your faxes in PDF format, you will need the full version of Adobe Acrobat (or a similar program) to annotate your faxes. If you are receiving your faxes IN TIFF format and you are using a Windows PC, the TIFF viewer and editor that comes bundled with Windows will allow you to annotate your faxes.
If you have your signature in the form of a small image file, you can use the annotation features mentioned above to add your signature to a fax without the need for printing and scanning.
I have an existing fax number that I have been using for years with a conventional fax machine. How can I switch to GreenFax and keep my existing fax number?
We do not have the ability to port your existing fax number onto our network. However, your local telco service provider who carries your existing fax number probably offers a 'call forwarding' feature, which can be used to redirect incoming calls on your existing fax number to your new GreenFax number, while retaining ownership of your existing phone number.
Many telco provider offer an option to drop your phone line, but keep the phone number with call forwarding for a nominal monthly charge. Check with your local telco provider for pricing and details.
Can I receive faxes on my wireless device?
If your wireless device is capable of receiving email and opening PDF or TIFF documents, then you can receive faxes through GreenFax on your wireless device. For more info, please see section 'Reveiving Faxes on Wireless Devices' in our user guide.
