Are there Fax machines that work with broadband phone lines?
Are there Fax machines that work with broadband phone lines? Similar to Vonage or Comcast.
I am aware of the pay services but i’d like to have my own for my home office.
Thanks
I am not aware of Fax machines that are specifically designed for VoIP access directly over IP.
But, generally speaking, regular Fax machines “can work over VoIP” broadband connections if the following criteria is met:
1. The VoIP service provider supports G.711u and/or T.38 Fax codecs.
2. The VoIP ATA phone adapter you are using is capagle of G.711u “Pass-through” and/or it directly supports T.38 Fax Codec.
Comcast suggests that Fax will work on their network:

Vonage suggests that Fax will work on their network:

(they recommend using lowest speed of 9600 or lower)
T.38 is the only VoIP Codec that is designed specifically designed to only handle Fax transmissions. Comcast and Vonage do not specify if they use T.38 codec or if they are just using G.711u Pass-Through.
The Linksys SPA2102 VoIP adapter supports not only G.711u Pass-Through, but also is designed to handle Faxes by implementing T.38 Fax codec. But, for T.38 to be viable, your VoIP provider also needs to support T.38 codec. CallCentric is one VoIP service that I am aware of that specifically state in their FAQ’s that they do support T.38 Fax codec handling through their service.
I use the Linksys SPA2102-NA user configurable ATA with various VoIp services. It is a 2-line ATA. This makes it convenient to configure Line-1 for Voice calls and Line-2 for Faxes.
