[asterisk-users] Possible Bug? .call files executing multiple times

[Brandon Phelps]

Hello all,

We are setting up an auto-dialer to call customers based on the opening 
of tickets in our internal ticketing system.  Everything is going fine 
so far except for one snag:

To test the system we are implementing I am manually moving .call files 
into the /var/spool/asterisk/outgoing directory like this:

asterisk at dialerdev:~# cp test5703.call /tmp/test.call && mv 
/tmp/test.call /var/spool/asterisk/outgoing/

This works great and the call is immediately started, however more often 
than not (ie. not all the time, but most of the time) after answering 
the call or rejecting it (sending it to voicemail), another call is 
performed using the same file.

I notice that when a call is initiated the .call file is not removed 
immediately.  Instead, asterisk waits until the call is completed before 
removing the call file, so it seems like 5-10 seconds into the call 
since the .call file still exists another call is placed.

Any advice on how we can avoid this situation and ensure that only one 
call is made per .call file?

The OS is Ubuntu 11.04 server and we're running Asterisk 1.8.

Thanks,
