<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There is already a reference to 'faxdetect' in use here (the one created by fax_detect_new()) which hasn't been released. Why is another reference necessary?
On the line 'fr_hook.data = faxdetect;' that reference is *transferred* to the fr_hook structure.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">this ref is droped by the caller the reason is to allow a program to set up a framehook and then
hold the ref checking returned results after the framehook is gone this may not be required latter.
it also prevents a race condition as im returning the pointer i only unref when ive had my way with it.
the other ref will be held in the framehook while its active it may die at any time. </pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The intention here would be more obvious if the ref count was incremented when you set fr_hook.data = faxdetect. It may also be better to increase the ref count in the ATTACHED event handler inside of the framehook it self.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hi there the patch that was going around circa 2008 to implement this in 1.4/1.6 app_fax has been moved to trunk [1.10]
ive made some cleanups and moved it into res_fax res_fax_spandsp this is the framework and not production code
unfortunately i have no means of testing it at the moment and require help.
i have cleaned the code up substantially it is related to R459
hope this is found useful and aids in the goal to get it in 1.10.
Adds application FaxGateway / FaxDetect
Adds alternate bridge to Dial with new option.</pre>
