Problems with Efax

[fixit7]

I can not get a successful fax using Efax-gtk.

Looking at the red highlighted line, it looks like it was sucessful.

I found this.

If your telephone line has DSL Internet service (on the same telephone line where your fax modem is connected to)
you may require to install a DSL filter between the fax modem and telephone connection.

After installation of the DSL filter, no more fax problems.
