If the registered UA is alive, pinging before every usrloc (e.g.
OPTIONS) you just increase the call setup latency.

If the registered UA is not alive, I'm afraid I don't see the
difference between pinging before every usrloc (e.g. OPTIONS) and
sending the corresponding INVITE- you still need to handle timeouts.
