Having a problem with Windows Fax and Scan on Small Business Server 2011 Standard SP1. When I call the fax number, I can see the line ringing in the Fax Status Monitor, but it errors out with "The incoming call cannot be answered as a fax call". I've also tried sending and receive an error: "No dial tone was detected" I've connected a regular phone to the line and placed an outside call and received a call from an outside line. No errors are logged in Event Viewer, but If I check the Server Roles, Fax Server shows Event ID 32092, 32032 and 32031
Troubleshooting so far has consisted of:
Restarting Fax service
Removing/Readding the Fax Account in Windows Fax and Scan
Checked Print Spooler and Fax queue for held documents to clear (none)
Uninstalled/reinstalled the fax modem in Device Manager
Run Windows Update(several security updates pending)
Checked the DeviceToMonitor key in HKCU to HKLM\Software\Microsoft\Fax\UserInfo matches the DeviceName key in HKLM\SOFTWARE\Microsoft\Fax (at one point it did not match)
Removing/Readding the Fax Role. In the process, also removing registry keys: HKLM_SOFTWARE_MICROSOFT_FAX, HKCU_Software_Microsoft_Fax, HKLM_SOFTWARE_Microsoft_Windows_CurrentVersion_Telephony_CountryList, HKLM_SOFTWARE_Microsoft_Windows_CurrentVersion_Telephony_Locations.
At one point or another, I have already reviewed the following links:
Please let me know if anyone has any other suggestions.
