If you purchased something on eBay and it has been less than 30 days, open up a case as an item not as described to return it for your money back. It doesn't matter if it was listed as no refund--you should still be protected provided you open up a case in 30 days. If not, you are out of luck.
If you follow Steve's advice (which I recommend), consider an OBi202, which is currently being sold for $62.99 on Amazon. It provides for two ports--which is nice to have concurrent call management. For the difference between the current cost of the OBi200 and the OBi202 on Amazon, it really is worth the investment in the 202.
