[asterisk-users] Country numbering plan resources

[Alex Balashov]

What's more, the "official" numbering plan authorities' information 
doesn't provides even less insight into the cost structure once you take 
into account that different underlying carriers have different ways of 
delivering calls to different mobile providers.

For instance, yes, it is a general rule that termination to mobile 
providers is more expensive than to fixed-line pretty much anywhere. 
But what if the underlying carrier isn't delivering it through an 
incumbent tandem but has a private interconnection (on different terms 
than standard handoff) with that mobile carrier because they pass enough 
traffic symmetrically?  What if they do bill-and-keep?  Now what's it 
matter?
