Voice call


i´m new in programming modems.

I want to establish a voice call with a AirLink Fastrack Xtend EDGE FXT009 modem, which is connected to my computer via USB.

I start the call with the AT-command: ATDnumber;

Now i don´t know how to transfer the audio from my computer to the modem.
Can anyone help me to slove this problem?

Greetings Daniel

You would have to use the souncard’s audio in/out to connect to the Fastrack’s audio in/out.

Check the Fastrack User Guide for audio levels, pinout, etc…

Thank you for the answer.

Over USB it isnt possible?
