Does anyone know of a tool to use to analyze analog fax transmissions - T30. asked 31 Jan '14, 08:57  fax |
One Answer:
Well, this is really not related to Wireshark! Why? Because you want to capture and analyze ISDN or analog signals, carrying the T.30 protocol. So, you need a hardware T.30 analyzer. How do you find one? Answer (to your question): invest 15 seconds to google it: http://bit.ly/1ihrlGu See also here: http://ask.wireshark.org/questions/22391/decode-packets-as-t30-messages-in-wireshark Regards answered 31 Jan '14, 11:09  Kurt Knochner ♦ |
Kurt;
Thanks for the reply. tone not neccesary. I invested more than 3 hours searching and only found 1 real sotuion which is $7,500.00 just for the basics. Not knowing where Wireshark was going with R&D and knowing that you could handle T.38 I decided to see if there was an option for this within WS.
Never mind, just my kind of fun/humor ;-)) I hope my Google link was helpful.
It's not going anywhere that involves developing hardware. :-) That's not what we do.
If somebody else develops a hardware device that can plug into a host and supply to software running on the host the "Binary coded signal functions and formats" described in section 5.3 of T.30 (well, I have some pre-publication version, so maybe the section number changed), then it might be possible to have Wireshark (or libpcap/WinPcap, with Wireshark using that) get those HDLC messages and analyze them. If a fax modem card can do that, great; if it takes a $7,500 hardware device, I guess with a suitably-modified version of Wireshark (and possibly libpcap) plus $7,500, you could do it.
