I finally managed to write the captured payload data to a file. I can playback the audio now using aplay -r 8000 -c 1 -f S16_LE test.wav If you send the AT-Command "AT^CVOICE?" to the card then it will answer with "^CVOICE:0,8000,16,20" it is also possible to change this setting. So I think that the card should be able to output other audio formats too (like 3G wideband audio), but I have not tested this command out. The next thing to do is to find out how to make the UMTS-Card output sound without using the "Mobile Partner" application.
