I've recently had my 2talk automatically block international calls a couple of times. There have been occasions when multiple calls were apparently made to odd locations at, sometimes, odd times (for either the destination or the source). Many of the numbers seem to be doubtful valid numbers (in one case two were the same apart from one had a country code prefixed).

2talk are claiming it's tall fraud but I just don't see it. most calls didn't cost anything and a couple, that did connect, overlapped, from and to the same numbers. Most that connected were very short and the rapidity with which the calls were made just didn't seem possible (except maybe with software, but to what end?).

Does it seem reasonable that 2talk's explanation is valid, or is it more likely that their call record system is going bananas every so often?

They've suggested I get a new router, but for what reason I don't know.

Discussions ongoing, but all comments welcome.
