[Asterisk-Users] Channelbank Recomendation and GS102 question

[Jonathan Moore]

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. Many refs to TA 
750s.
