That's 13.8 minutes per call. Pretty good going for a call center! It's 
probably tech support, I suspect mass phone marketing as a much lower 
ACD than this =)

Some gateways such as Quintum have the ability to automatically failover 
PSTN when speech quality becomes unacceptable. That might be what you're 
looking for... you'd still get some substantial savings by doing LCR & 
using multiple VoIP providers (ibasis, vsnl, teleglobe...) AND you would 
still get decent speech quality at all times.

Mind you, with this kind of volume, you might be able to negotiate 
pretty good deals over TDM anyways... it's what the VoIP players do: 
collect traffic to try and build volume so they can get better deals. 
Since you already have the volume (okay, 5MM is tiny in the grand scheme 
of things, but still pretty good going), and don't have a multi-site 
setup, VoIP might be lots of migration work and get you little in return.

And if it's a multimillion dollar operation, it's not like you can toy 
around with it too much either...

Cheers,
Jean-Michel.
