At startup we actually do output messages about what transports are
available and what the resolver will check. We could extend that to runtime
as well.

For TCP the PJSIP stack requires it in order to work, and to allow
connections back in case the remote side doesn't do connection reuse. For
UDP there is no such thing as a connection so you need something listening
to receive incoming traffic.
