This may have limited applicability, but I thought I would put it out there. I have purchased three units that were listed as the OBI212 with FXO and FXS ports. Further I have seen multiple listings Claiming to be the OBI212, but pictures showed a label for the OBI202, which is much cheaper and does not offer the dual port type configuration.
I have messages the sellers about changing the listing and everyone has responded that the item was as pictured.
No offer to revise the item main description.
The point of all of this is that if one is going to buy an OBI212, it is very important that you verify with the seller that what you are buying is in fact the OBI212 ant not the much cheaper OBI202. I don't know if it is allowed (likely not) to post vendor names that are using misleading item names, but I can easily provide a list if it is acceptable and wanted.
Bottom line is "Buyer Beware" if looking for an OBI212
