Where does __func_periodic_hook_context__ come from?

Question

Asterisk

In /etc/asterisk only:

localhost*CLI> !ls /etc/asterisk

Why, or where does this __func_periodic_hook_context__ come from?

I found the only mention of it on https://reviewboard.asterisk.org/r/3362/ , but how it got into my dialplan is not clear to me. Nothing bad will happen if I turn it off via noload?

Answer 1

Yes, I did not pay attention to the generated contexts - this functionality appeared. If you don't use it, feel free to disable it.
