We're currently running 1.4 r48326 - a little while before the full 1.4 release. We are having some problems (crashes) with attended transfers and some other stuff, and was going to move to the latest svn 1.4 as I beleive that the attended transfer bug has been fixed. However, I note that #8763 (http://bugs.digium.com/view.php?id=8763) has some problems with the zap channels in the 1.4.0 release (which we *don't* have). My question is, are the problems with zap also theoretically present in r48326 (it's just that we don't have them) or were they introduced after r48326 (and therefore we will have them if we upgrade). Any thoughts / takers / advice ? Julian.
