Why Hosted Faxing Beats VoIP For Fax

Fax Over IP

During my first year of graduate school, I was using the department copier one day to make handouts for my class. While the machine whirred off my pages, one of the professors came into the small room where the copier was kept. I stumbled all over myself to make space for him, pushing my things aside and nervously telling him I would be done momentarily.

“It’s okay, lad,” he said to me in a heavy English accent. “I don’t use the copier. I am here for this.”

He pointed to an antiquated ditto machine in the corner of the room. He cheerfully proceeded to operate what I had assumed was a forgotten piece of office equipment. I was fascinated as I watched him spin the handle of the machine, producing pages with nearly illegible text that slapped into an inky, wet, slightly malodorous pile. 

The ditto machine was inefficient, dirty, and — I clearly remember thinking — a complete waste of time. I could have printed 200 copies of my handout by the time he had spun two dozen pages off that drum. I had often heard of people going to great lengths to avoid change, especially technological change, but seeing it first-hand like this was a revelation that bordered on the comical.

Choices for Fax Solutions

Companies burdened by aging fax infrastructures often act like my professorial friend, clinging to outdated technologies while ignoring better alternatives. And no wonder — these companies often boil their choices down to two mutually exclusive, and not very appealing, possibilities:

1. Perform expensive hardware and system upgrades in-house. (The “reinvent-the-wheel-at-our-own-expense” option.)

2. Adopt a telecom-based solution that may or may not fit into the organization’s current business model. (The “square-peg-in-the-round-hole” option.)

The first choice usually is dismissed quickly once the numbers are crunched. Provisioning multiple servers with upgraded fax cards can run into the tens-of-thousands of dollars. Add to this expense additional application servers, licenses and fees, utilities, dedicated fax lines, data storage, service contracts, and IT resources to care for it all, and the cost of upgrading even a modest in-house fax system can be prohibitive.

The second choice seems a more logical course. Companies that look into newer telephony technologies such as VoIP (like Vonage or MagicJack) are impressed by the savings garnered by eliminating dedicated voice circuits and sending their voice traffic across the internet. Naturally they would like to extend that same savings to fax. Yet, the promise that VoIP brings to voice does not translate completely to fax.

The Problem With VoIP For Fax

VoIP calls are broken into individual streamed data “packets” that follow various routes across the internet before being reassembled at the call destination. If one packet is lost, it is usually not perceptible to the human ear; or if it is, then it is heard as a very brief moment of silence in the conversation. While this “jitter” is an acceptable error situation for voice, it is not for fax. Silence causes havoc for fax machines, causing them to disconnect or lose track of what is being transmitted. Dropped packets translate directly to fax pages with missing data, lost pages, or mishandled transmissions.

The latest generation of fax machines attempt to combat jitter with silence suppressors and Error Correction Method (ECM) techniques, often with mixed results. Silence suppression can inadvertently block the fax signal by misjudging when the signal starts and stops. Machines employing ECM can request that a fax transmission be resent so that missing data makes it through. This only increases the overall cost of the fax, and is no guarantee that the ensuing transmission will be jitter-free.

Businesses that have adopted VoIP and want to use it for faxing often end up encouraging their carrier to adopt the latest specifications for faxing over VoIP (or FoIP). The problem with these specifications — known as T.37 for Store and Forward FoIP and T.38 for Real-Time FoIP — is that they are too loosely written to be adequately and universally implemented, and so the carriers tend to avoid them altogether. This leaves customers having to settle for spotty fax service from VoIP providers that don’t have a true FoIP solution. Even if a VoIP provider does offer fax services based on these specifications (or their interpretation of them), the customer must upgrade their fax equipment to the latest generation of machines, since the new specifications don’t work with older, analog fax equipment.

Hosted Faxing to the Rescue!

Fortunately, small-to-medium sized companies don’t have to settle for expensive system rebuilds or ill-fitting services when considering how best to use fax. Hosted (“cloud”) online faxing solutions such as eFax® provide base plans with the option to pay for extra usage as needed, which supports lean business strategies. These solutions provide a flexible, digital service for sending and receiving faxes by email using your PC, laptop, smartphone, or tablet. Furthermore, they replace expensive in-house fax systems with a predictable cost model and capacity that scales to your organization, whether you have five employees or 5,000, or send one fax per day or 500.
