<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 will not work.
For an interception routine, the change will always be blocked. The interception routine must operate on the channel's copy of the connected line information. When the routine is complete it ast_indicates the channels information to the channel driver. This code is then going to see no change and block it.
Unless the channel always keeps a copy of the last ast_indicated version lying around, the channel driver must filter out the duplicates. Chan_dahdi already does this because it needs to keep a copy anyway. Chan_sip should do this as well as chan_pjsip.</pre>

Old code which is no longer required has also been removed.</pre>
