For business use, I would suggest you first find a BRI card you can use here in the states. Hint, bug Kapejod into making that 4 port card US ready. Then move any business user over to BRI if they want small deployments. The 8 lines you can get by one 4 span board from Kapejod would be wonderful for a small business and it gives you answer and disconnect supervision. It will give you a lot of other benefits that analog can't. That also would go a ways to making a more reliable from the wires standpoint system as well. I doubt you will have as many unexplained problems from a BRI circuit. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
