I just went through this cycle. I did go ebay and went with a Carrier Access Access Bank I, since I still haven't decided if this will be our production system and I didn't want to invest too much to find out. After fighting with it all day today, I would not recommend the AB1 for this application -- both inbound and outbound calling, because the AB1 doesn't support call supervision on the inbound fxo ports. And their tech support says that Carrier Access does not sell a model with call sup. There are various work arounds, but I think not matter what it would be more functional to have a channel bank that supports call sup. I also think there are issues with some CBs and caller ID. If you want caller ID make sure to ask that it is supported and with which cards.
Adtran seems to be the most recommended vendor on the list.
