Has anyone tried faxing over VOIP via a regular fax machine and ATA adapter which supports the T38 protocol? Does it work?
I read about it here:
If you want to continue using your old fax machine, and you want to connect to your VoIP phone system, its best to use a VoIP Gateway and an ATA that supports T38. T38 is a protocol designed to allow fax to ‘travel’ over a VoIP network. An example configuration of such a setup can be found here
