There are no real examples that would address your points. The
primary reason is that your * can dispatch a call to a provider
and the provider will accept that handshaking call. But, if
they are having internal call-completion issues, there is no
way for you to know that. You could get some sort of busy,
dead air, etc.

You could probably design some sort of timer-based timeout,
but what indication would you use to indicate the call was
successful vs unsuccessful?

There are several ways to address whether your * is successful
in reaching your provider's equipment, but that's about it.
