I posted it a while back, I just want to know if it is possible, because I am really in need of this for my node.

I really need to transmit a sequence of DTMF tones when a link disconnects, but ONLY when all links disconnect. 

So if two links are connected, and one link disconnects, there will be still one node to the server, thus it shall not transmit any tones. When the second node disconnects, there will be Zero nodes left, therefore, it will need to transmit the sequence. 

Any ideas?

73 everybody, and thanks for any efforts or help for a solution to this.
