<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This isn't going to work because interval hook objects change as time passes and they have a sequence number that must be consistent with the features struct. You have to create a wrapper interval hook and use ast_bridge_interval_hook() to add it to the into features struct.
Though it would be nice to do it in such a way that the wrappers won't accumulate. As you have this now, there would always be two wrappers when the interval hooks actually get used. One for merging the hook to the channel datastore. The second when merging the hook into the active bridge interval heap.</pre>
