Sorry but the cause of your issue could be as simple as a failed modem, and the cause is not evident in your post.
Hello, I use Windows XP, Service pk 2 has been installed,I connect to the internet via cable modem (motorola SB5100 series) , normally I have a telephone cord pluged into back of my computer that I connect directly to my phone line (land line).A Connexant 56K Data/Fax Modem , I also have in . When I would fax I could not only see a small box open showing the progress or fax status . I would also hear the ringing until receiveing line picked up to accept my fax. Recently I have not been able to send faxes. When I go to fax console and then outbox my fax attempts are there with red circle with x in it . Upon opening properties of a outbox fax the extended status reads "fatal Error" , along with JOB ID: 0x0201080a30b2a429, Broadcast ID:0x2001080a30b2a1b8. Not that this means anything but I figure I 'll give as much information as possible.
I have had off and on difficulties with my fax but usually I am able to resolve them myself , not so this time and I have been working on it more that 2 weeks.If there is anything else that needs to be known about my system please let me know. Thank you all for your attention !
