Hi,

I looks like this is a problem on 1.8.x only. I have a 1.6.x system bridging 
to SIP and more and I don't see lots of unref'ed structures.

It appears to me that the Asterisk API has changed, and now needs a final de-
ref, by the allocator of the call structure. Could you try this patch, on a 
non-production system and see what happens:
