Hi, 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. Skyler KDØWHB
