I have a Windows Server 2008 R2 FAX Server that intermittently terminates faxes mid-sending. The error message is "The remote fax machine did not respond in time, and the call was terminated." This typically happens when sending large faxes, (i.e. 30 - 100 pages in length). I have not seen this occur with faxes of a few pages in length. The problem is that I have seen successful 96 page faxes go as well, which is making this hard to figure out. Also, the faxes in question are going to one fax number in particular. I watch the sending page count as it is being faxed, and I'll see 8 or 9 pages being sent in windows fax and scan, and then it fails with the aforementioned message. If I then print the faxes and send them to the same fax number using a traditional fax machine, it completes without incident. The server is Windows 2008R2 and is running Fax Services being accessed via Windows Fax and Scan. There are 2 modems attached via PCI and 1 USB modem attached for a total of three. Any help would be greatly appreciated.
Thanks!
