[VoiceOps] Geographic redundancy

[Alex Balashov]

I didn't say that the presence of IP removes all the complexity, nor 
that interconnection without TDM and/or SS7 is possible--at least, for 
CLECs, but also many ITSPs that buy TDM in order to do access that is 
actually reliable and interoperable.

My intended point, which should have perhaps been made clearer, was only 
that the use of more IP - where feasible and practical - in the place of 
a circuit-switched alternative can add fluidity to the network that can 
change the CAPEX formula for redundancy in a more favourable direction.

It's not magic and it certainly won't solve all the problems that 
motivate the original question.
