Thanks for your detailed reply. Can we agree that there is a difference between CDRs and provisioning info? No one will complain that you are obeying the law with respect to the latter, but "never" is a strange call record deletion policy. Not even an ILEC would try that. A policy this strange will cost you customers, especially since anyone trying this service is much more likely to think about privacy issues.
That's a fair perspective and I will give some sincere thought to the prospect. Striking a balance is important to us as a team, so I can't say I will cater to everything you wish, which I'm sure you understand easily enough, but I do wish to treat it with the weight it deserves when you're being very reasonable about explaining your position. Cheers.
