If I had this problem, I'd use ethereal to observe the sip traffic to
the box and look for a control packet containing "RING". If that is
coming from your asterisk box "after" a call in progress, then asterisk
isn't functioning properly. 

If you don't see that packet, then I'd be on the horn to sipura support.
(Make sure you're running the latest firmware for the box as that will
always be their first suggestion.)
