Basically it works like having ISDN dialup with a lot of bonding. When asterisk notices more than X lines idle, it dials up the other side and sends it off to ZapRAS to bond the channels in. If asterisk notices less than X channels free, it disconnects one of the ZapRAS channels. Bandwidth is then in units of 64K connections. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
