<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">state->last_hook is never pre-initialized to ast_tvnow(), so hooks would always trigger on first check after being created or re-enabled. Unless this behaviour is documented I would expect the first run after create or resume to be delayed state->interval seconds.</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;">Fair. I had originally intended for it to run immediately, but I think it makes more sense to delay.</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;">So is the implication then if I were to set the interval to 30 seconds that the hook wouldn't run for 30 seconds and then run every 30 seconds? That seems more counter intuitive. I'd think that it should run and then repeat every interval seconds.</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;"> This commit introduces a new dialplan function, PERIODIC_HOOK().
It allows you run to a dialplan hook on a channel periodically. The
original use case that inspired this was the ability to play a beep
periodically into a call being recorded. The implementation is much
more generic though and could be used for many other things.
The implementation makes heavy use of existing Asterisk components.
It uses a combination of Local channels and ChanSpy() to run some
custom dialplan and inject any audio it generates into an active call.
The other important bit of the implementation is how it figures out
when to trigger the beep playback. This implementation uses the
audiohook API, even though it's not actually touching the audio in any
way. It's a convenient way to get a callback and check if it's time
to kick off another beep. It would be nice if this was timer event
based instead of polling based, but unfortunately I don't see a way to
do it that won't interfere with other things.
