Re: Back to worst-case-scenario to start with!

How it occur with the smaller providers, if nearly every over provider that is much smaller than CallCentric is employing geographic redundancy? Both Anveo and voip.ms have a multi-server setup across the world.

Add Future Nine to that list.

The problem isn't that it's hard or expensive to do it (it's not) - the problem is that CallCentric is using proprietary systems that make it hard and expensive for them.

I'm not sure of what CallCentric is using for a switch, but from what they've said in the past, it's carrier grade telecom switches (most likely Lucent), connected to an SS7 and most likely TDM network. That's not any more "proprietary" than an Asterisk server. More expensive to make redundant - definitely, I can't argue that point. Which one is better? When all hell breaks loose probably the Asterisk box!

Edit: this isn't meant as an attack on Nitzan on F9, just saying there's different ways to do things, and one isn't necessarily and better/worse than the other. They bot have advantages and disadvantages depending on the situation.

They're also doing their own switching and interconnecting with actual telecommunications networks. Whereas, these Asterix box providers are basically reselling services and using trunks wholesaled from other providers and are essentially tier 3 voip providers.

What you have to understand though is that those systems are much more complicated. If it were as simple as you have stated, then why are all those Verizon CO's still down and no one has phone service? They should have a backup system on the other side of the country for all their interconnects.

FutureNine has had its own failures, as I recall.

I like and respect you, but sometimes you say that CC systems are proprietary, and at other times you say that their systems aren't much different from anyone else's.
