[VoiceOps] SS7 Landscape

[paul at timmins.net]

The question was (essentially) about mitigating the impact of an SS7 outage (disguised as a question about who provides SS7 these days (nobody, if they can avoid it)). If the SS7 links go down and you only have a small amount of your traffic affected, I call that a huge win.

I don't have to go to Chicago and back to get to the operator in the next row of racks over. Though, I suppose my SS7 diversity and availability is the weakness, not the actual call path.
