<span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; color: rgb(51, 51, 51); ">I am wanting to use the ISDN cause code on an Asterisk 1.6 server to determine the status of a call attempt, where the call might not actually connect. Reason is I am checking for valid telephone numbers from a list of numbers, and I would like to know if the call has answered and cleared which I can by writing the hangupcause variable, but where I get an out of order network message, or number doesn't exist, I want to capture these ISDN cause codes where the call might not have connected and started the dialplan extension. <div>
