I get a similar problem with a domestic analogue line in the UK. I *speculate* that there is a short half ring being sent for some reason (line test or similar), but my card (Digium) seems to need about 5 seconds to detect hangup on the remote end, so I get a phantom 2 rings at my end and then it stops... No solution, but thought it might give you something to consider...
