I have just purchased a Siemens TC45 GPRS-module. Now I need to decode audio from the audio interface and send it to a server over GPRS. Is this possible with the TC45 alone, or do I have to buy some additional hardware? I am planning to write my software in J2ME. I have tried to find code examples for this but without any luck. As you can see I am novice to this and J2ME, so any help will be highly appreciated. What should my next step be?
