Yes, exit the child and have the supervisor's restart strategy do it's job.

You could set the restart strategy of the above udp_sup to be
'rest_for_one' which would kill all the other workers when it died.
However that would have the side effect of kill stun_worker and
srtp_worker when dtls_worker exited.

The right way is to have a seperate supervisor for
[dtls|stun|srtp]_worker as a sibling to udp_worker.
