It's important to realise that the fundamental business of telcos is billing, and that's the central, required area of expertise. Carrier interconnect is mainly based on termination fees. If I receive a call over my point of interconnect with carrier X, you'd think that it'd be in my interests to know the call's genuine origin since otherwise I don't know who to bill for it. But in practice (depending on the interconnect agreement) I probably only care that I received the call from carrier X, and the call origination data is only important for resolving future billing disputes with them. If carrier X originally received the call from carrier Y, then they similarly probably only care about logging the entry point of interconnect so that they can bill for it. Again, accuracy in the origin number is only as important as the risk that the dollar amount associated with receiving call will be disputed. When it comes to customers, telcos only care about giving good enough caller ID that meets regulatory requirements and reduces customer churn to something manageable (i.e. manage the customer anger so on average people don't walk). There's no money in sweating the small stuff, and there's a loss of revenue if you reject the inbound call because you're not happy with the originating number signalling. None of this is a recipe for accuracy. It's all about money. Joe _______________________________________________ IOZ mailing list [email protected] http://lists.internet.org.za/mailman/listinfo/ioz
