And back again with the fax component of Aastra's Unified Messaging. The client has a fully functioning UM setup and the fax plugin works on all computers...except one! After numerous formats, repeated Windows updates and following the troubleshooting error I had previously posted, I have found out the following:
1. Windows fax is the basis for Aastra fax.
2. If Aastra fax installs and communicates with the server, and DotNET is installed, and still NO faxes are sent, the underlying Windows fax server is faulty.
3. Uninstall the Aastra fax plugin and delete Aastra fax from "Printers and Faxes".
4. Install a Windows fax console (make sure a modem is present) and test it.
5. When Windows fax is working, install Aastra again and it should work fine.
