Carlos & Joel, It looks like you're correct. It is taking exactly 32 seconds, as described in the RFC (http://tools.ietf.org/html/rfc3261#section-17.1.1.2), for the call to enter the disconnected state, and for the Call object to be destroyed. I think I'll just have to set max calls a bit higher than I anticipated.
