Two managed services? I'd prefer not to digress to
PBX's. The ss7 component more interesting, and, I would 
find arguing the technical merits of the solution more 
satisfying than arguing with google queries. The only 
think interesting is that they are supporting the theme 
of the thread, 911, $call proto, and SS7, all dependant 
on each other 

YMMV, but I think I've reached my public 
posting limit for the day.

Best,
