I think this is one area where, as indicated earlier in the thread, a lot of
development effort would be needed to obtain that extra degree of reliability.

two, VoIP can compete with the PSTN in reliability. My (limited) understanding
is that PSTN equipment typically achieves 99.99999% uptime, and if VoIP
systems are going to play in that arena, it would be desirable for
free/open-source software to do so.

If FreeSWITCH itself is working correctly, all you need is a hardware failure
or a kernel panic or a network outage to drop that up-time substantially, not
to mention dropping the calls as well, which I've never experienced as a user
of the PSTN due to equipment at the telephone exchange.

I have, however, experienced some rather low-quality PSTN calls over
international lines, which have the added disadvantage of being expensive to
