[VOIPSEC] RE: TLS as the SIP security mechanism

[Dave Pascua]

For true reliability, I'll stick with good old PSTN service.  I can
make phone calls during major blackouts because those expensive telco
techniques were applied.  I highly doubt I can make a successful DNS
lookup during a major blackout, although I can't say that I've
tried...

Cheers,
