This is the first month we've put a couple of our customers onto A2B. System is generating some 12,000 calls a day. A2B is working flawlessly and with minimal load on the system. This is simply the best product we've tried.

Hats off to asiby and Stavros for their help
Edit:
Having read some of the comments regarding success stories with suggestions that donations be given as they're making 'so much money' let me say this.
A2B in my view is fundamentally solid. However some of the UI's are quirky and buggy in some areas, and are less than intuative.
My company's contribution will be to go thru the UI's, highlight issues where possible, and given time, fix them for the benefit of the community
