Attractel is an all-solution VoIP (Voice over Internet Protocol) company founded in 2005, specialized in developing VoIP applications, mostly based on the Asterisk open-source PBX project.

If you will notice, there have been tremendous amount of applications and gadgets to make VoIP a lot easier to use for our day to day work. However, what VoIP could not offer was faxing, faxing over VoIP is practically impossible for one simple reason: VoIP telephony cheapness is achieved through compression of signals for the sake of making more calls with less bandwidth. This means that voice data gets compressed to travel to the other side, where it gets decompressed. This is performed by codecs.

One of Attractel’s products is the Faxterisk, a commercial software solution to support T.38 fax support to your Asterisk.

This is how Attractel’s Faxterisk works

  • A fax terminal passes analogue data to a T.38 gateway
  • The gateway takes the signal, demodulates it and transmits it over the existing IP network to another T.38 capable device(e.g. Internet Aware Fax(IAF) or a compatible Analogue Telephone Adapter (ATA)) or another T.38 gateway that modulates back the digital signal and sends it over the PSTN to another fax terminal.

From Attractel’s website:

The sensational part of our Faxterisk solution is that it is actually a far more reliable faxing method than traditional analogue faxing. This is not a phenomenon; it is due to the fact, we may want to believe that landlines are good carriers, but this is far from true as far as greater distances are concerned. IP networks are more reliable carriers over long distances and with our FoIP solution, you will inevitably enjoy faxing more than ever!

 

The Faxterisk package includes:

 

  • T30faxRX for receiving normal faxes over PSTN
  • T30faxTX for transmitting normal faxes over PSTN
  • T38faxTX for T.38 fax origination (IAF fax)
  • T38faxRX for T.38 fax termination (IAF fax)
  • T38gate for FoIP gatewaying

There is no need to change anything in your Asterisk’s dial plan if you install Faxterisk. Faxterisk detects the fax signal and automatically switches to fax mode, which makes it most convenient for your working process.

NOTE: Faxterisk works with Asterisk* 1.4.X versions only.
