How do big carriers handle these kinds of scenarios
where a sudden outage in
a key component would cause calls to be dropped? Is this the achilles heel
of voice? Is there special kind of software or hardware (or both) for
handling these kinds of scenarios?
See

for example.
Your specific concern:
"Both our deployed SEMS (thanks to the Frafos Team) and our deployed RTPEngine
(thanks to Carlos) use a Redis-Database for storing information on the current
calls, however in both cases through a proprietary extension. The Redis-
database is distributed among the two servers, so if we start the services on
the passive node, all sessions can continue without service interuption."
