Generating a tone w/ cadence is a piece of cake. *Detecting* a tone and cadence is a bit trickier. Nothing in FreeTDM (that I'm aware of) can detect both tone *and* cadence, which is why it works great in the US (which uses a combination of tones) as opposed to Mexico (which uses, I think 425Hz for everything).<div>

<br>
You could try the dialplan application tone_detect to detect the busy<br>
tone and hangup.<br>
