Question: My fax machine was working with my Vonage phone line before – what changed?

Fax is a problem over VoIP because of how the VoIP phone line changes the audio signal to digital. A change in the VoIP environment can result in a transmission that worked no longer working.
Larger page counts, more graphically intense documents, changes on the internet, and changes with other fax machines can cause problems with the fax.
