Re: Bye Bye Fax

Sorry, I thought it was obvious that my specific issue with the Fax is that it uses a PSTN line (the main point of the article). I have no issue with a Fax implementation that uses SIP, or other digital methods.

It was obvious, which is why it got the reply it did, pointing out that a Fax which uses a PSTN line can equally use a PSTN emulator, that is, an analog to sip converter.

There is actually a bit of a problem: the common codecs used for voip aren't very good with FAX signals: they are specifically designed to discard data from voice signals that does not contribute to intelligibility. I don't know how important this problem is: I've heard conflicting advice, but it's all from people who (like the postings here) are pushing a particular point of view.
