<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">We have the possibly rather unique setup where we have cell phones<br>
posing as SIP devices. The SIP registration for those unfortunately<br>
doesn't go away just because the phone is off, since the registration is<br>
done by our cell-phone<=>SIP gateway, and that gateway has no way of<br>
knowing whether the phone is on or off.<br>
<br>
This is usually ok, but it gets problematic if the cell phone is a<br>
member of a queue. In that case Queue() keeps sending the call to the<br>
phone, and the cell-phone<=>SIP gateway dutifully makes a call, which is<br>
then rejected by the cellular network. A few seconds later, Queue()<br>
tries again. This needlessly wastes resources both in Asterisk and in<br>
the cellular network.<br>
<br>
One idea is to run the call through chan_local (we do this anyway<br>
because we need to format the caller-ID differently for different<br>
phones) and then record if a call is rejected, and for the next<br>
30 seconds just abort if we are asked to send a call to that particular<br>
phone. The downside is that we are still running a call through part of<br>
the dial plan, but at least it can be done in perhaps 3 lines of code.<br>
<br>
I would very much like to hear about smarter ways to do it.<br>
