TelCo switchs are not that present to deal with. Your method will work,
kind of. However, if the TelCo decides to send you a call during that split
second of idle, how are you going to handle it. The best way is still to call
your TelCo to take the span down. </FONT></SPAN></DIV><BR>

[asterisk-users] How to "busy out" zap channels<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>I know this topic came up many months back and some discussions were being
had on how to do this within the Zaptel drivers. However, I'm looking for even a
crude hack that someone has put together to get this done. </DIV>
<DIV> </DIV>
<DIV>We have PRI's and LD T1's that are load balanced on two boxes. The hunt
order goes from box to box as far as the spans are concerned. There are
times that I would like to busy one out so that calls gradually role to the new
box and I can eventually take one out of service. What I was thinking is to
create a script that I could tell the specific channels and it would go through
and initiate zap calls to an empty meetme. Basically bridging all of the
available zap channels on a given span together. Then the trick is monitoring
the hangups so that it can initiate a subsequent call immediately following.
Once all of the channels in a span have been bridged, I can then bring the box
down. Nasty huh? </DIV>
<DIV> </DIV>
<DIV>Anyone have a better idea? Or do they have anything like this so I'm not
putting it together?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
