i+=============	Err	parazyd.org	70
i+	Err	parazyd.org	70
i+http-listener is a small Flask daemon acting as a HTTP API listening for	Err	parazyd.org	70
i+callbacks from the FreePBX log handler.	Err	parazyd.org	70
i+	Err	parazyd.org	70
i+It offers callbacks for `/callanswered` and `/callended`.	Err	parazyd.org	70
i+	Err	parazyd.org	70
i+The former will mute the playback of our sound input on the speakers and	Err	parazyd.org	70
i+enable it on the phone.	Err	parazyd.org	70
i+	Err	parazyd.org	70
