Usb 3g modem to make/receive calls

I was looking for this precise post. Please bear with me - tell me the steps you took. My post is at this link: Voice call from PC with USB modem, SIM & close-talk headset
Do you use a Graphical User Interface and a particular Display Manager? What front end do you use? And if possible, could you list the relevant codes using the Code on the top of this editor? It helps very much, you know!

And how did you arrive at the point: [quote]…my config in the /etc/asterisk/dongle.conf is…:[/quote]
I use both Debian and Knoppix systems and don’t have Windows at all at home.
My deepest regards…
