Your problem is 100% related to the example you are testing and not
the real-world usage.

in your dialplan where you have:

<action application="bridge" data="loopback/wait"/>

change it to:

<action application="bridge" data="{ignore_early_media=true}loopback/wait"/>

This is not documented properly in the default config.
Without the ignore_early_media param the ringing stage ends as soon as
you get a 183 and the call bridges instantly assuming the far end will
be sending the media.
