title: How can i redirect my laptop mic to gsm modem input..?
body: <p>I am using <code>atd&lt;number&gt;;</code> command to connect a call and I want to play a <code>.wav</code> file into the phone call.  I'm playing the audio file and connected my laptop audio out to microphone but it is not audible at the receivers end.. Please help me to solve this problem...
